Delicious. Nutritious. Convenient. Two meals you prep once and grab all week — no sad desk lunches required.
You know that feeling when 1pm hits and you’ve eaten nothing, you’re starving, and the only option nearby is fast food you’ll regret?
These two meals are the fix.
Grilled Chicken Meal Prep Bento Box (sliced grilled chicken, cherry tomatoes, spinach, quinoa with chickpeas and cucumber, feta, hard-boiled egg, mixed nuts, and blueberries — all packed into one organized container) and Mason Jar Layered Salad (grilled chicken, shredded carrots, corn, cherry tomatoes, black beans, romaine, and a dressing that stays perfectly crisp until you’re ready to eat) are both built for real life.
Prep them on Sunday. Eat well Monday through Friday.
The mason jar salad in particular has a trick to it that most people don’t know — and once you figure it out, you’ll never go back to sad, wilted packed salads again.

Recipe 2: Mason Jar Layered Salad
Ingredients (makes 4 jars):
For the salad layers:
- 2 grilled chicken breasts, sliced (use same seasoning as above)
- 2 cups romaine lettuce, chopped
- 1 cup shredded carrots
- 1 cup cherry tomatoes, halved
- 1 cup corn kernels (fresh, canned and drained, or thawed frozen)
- 1 can (15 oz) black beans, drained and rinsed
- ½ cup red onion, thinly sliced
For the dressing (goes in first):
- 3 tablespoons olive oil
- 2 tablespoons red wine vinegar or apple cider vinegar
- 1 teaspoon Dijon mustard
- 1 teaspoon honey
- ½ teaspoon garlic powder
- Salt and black pepper to taste
Tools Required
- Grill, grill pan, or large skillet (for chicken)
- Medium saucepan (for quinoa)
- Large pot (for hard-boiled eggs)
- Ice bath bowl (for eggs)
- Sharp knife and cutting board
- Small mixing bowl (for dressings and seasonings)
- Whisk or fork (for dressing)
- 4 glass meal prep containers with lids (3-compartment style)
- 4 wide-mouth mason jars (32 oz each)
- Tongs
- Measuring cups and spoons
- Large mixing bowl (for tossing quinoa)
Pro Tips
Five things that make the whole system work:
- The mason jar layering order is everything. Dressing goes in first at the bottom. Then the sturdiest, most moisture-resistant ingredients (beans, corn, carrots). Protein in the middle. Delicate greens always go in last at the very top. When you flip the jar to eat, the dressing hits everything but never soaks the lettuce. This is the trick that keeps the salad crisp for 4–5 days.
- Cook double the chicken at once. Both recipes use grilled chicken. Season and grill all 6 breasts at the same time, then split between the bento boxes and mason jars. One cooking session, two recipes done.
- Let the quinoa cool completely before assembling the bento. Warm quinoa creates condensation in the container, which makes everything else soggy by day two. Spread it on a sheet pan for 15 minutes to cool fast.
- Don’t add the dressing to the bento salad section until right before eating. The spinach and tomato section should stay dry in the container. Pack a small dressing container on the side, or dress it the morning you eat it.
- Use wide-mouth mason jars, not regular mouth. You need to fit a fork down the jar. Regular mouth jars make eating an actual struggle. Wide-mouth makes the whole thing functional.
How to Make the Grilled Chicken Meal Prep Bento Box
Step 1: Cook the quinoa
Rinse 1 cup dry quinoa under cold water.
Add to a medium saucepan with 2 cups chicken broth.
Bring to a boil, reduce heat to low, cover and simmer for 15 minutes.
Remove from heat and let sit covered for 5 minutes. Fluff with a fork.
Spread on a sheet pan and cool completely, about 15 minutes.
Step 2: Season and grill the chicken
Rub chicken breasts with olive oil, garlic powder, smoked paprika, oregano, salt, and pepper.
Grill or cook in a skillet over medium-high heat for 6–7 minutes per side, until internal temperature reaches 165°F.
Let rest 5 minutes before slicing.
Step 3: Hard-boil the eggs
Bring a pot of water to a boil. Lower eggs in gently. Cook 10 minutes.
Transfer immediately to an ice bath for 5 minutes.
Peel and halve or leave whole for the box.
Step 4: Assemble the quinoa section
In a bowl, toss cooled quinoa with chickpeas, sliced cucumber, olive oil, salt, and pepper.
Add crumbled feta and fold gently.
Step 5: Pack the bento boxes
Divide equally across 4 containers:
- Section 1: Sliced grilled chicken over a bed of baby spinach and halved cherry tomatoes
- Section 2: Quinoa chickpea mixture topped with feta
- Section 3: Mixed nuts, fresh blueberries, and a halved hard-boiled egg
Seal and refrigerate. Good for up to 4 days.
How to Make the Mason Jar Layered Salad
Step 1: Make the dressing
Whisk together olive oil, vinegar, Dijon mustard, honey, garlic powder, salt, and pepper in a small bowl until fully emulsified.
Step 2: Layer the jars — order matters
For each jar, layer in this exact order from bottom to top:
- 2–3 tablespoons dressing (bottom of the jar)
- Black beans (dense, won’t absorb dressing)
- Corn kernels
- Cherry tomatoes, halved
- Shredded carrots
- Red onion slices
- Sliced grilled chicken
- Romaine lettuce (top — stays completely dry)
Press each layer down gently but don’t pack too tight.
Step 3: Seal and refrigerate
Screw the lid on tightly.
Refrigerate. Good for up to 4–5 days.
Step 4: Eat
When ready to eat, shake the jar vigorously to distribute the dressing.
Eat directly from the jar with a long fork, or tip into a bowl if you prefer.
Substitutions and Variations
| Original | Swap It For |
|---|---|
| Grilled chicken | Canned tuna, hard-boiled eggs, or chickpeas (vegetarian) |
| Quinoa | Brown rice, farro, or cauliflower rice (low-carb) |
| Feta | Goat cheese, Parmesan, or skip entirely |
| Black beans | Kidney beans, lentils, or edamame |
| Romaine in the jar | Kale (even sturdier, lasts longer in the jar) |
| Red wine vinegar dressing | Caesar dressing, tahini dressing, or green goddess |
| Blueberries in bento | Raspberries, grapes, or sliced strawberries |
| Mixed nuts | Pumpkin seeds or sunflower seeds (nut-free) |
Variation ideas:
- Mediterranean bento: Swap the chickpea quinoa for hummus, olives, roasted red peppers, and pita wedges alongside the chicken.
- Taco mason jar: Layer seasoned ground beef or chicken, corn, black beans, shredded cheese, salsa at the bottom instead of vinaigrette, and crushed tortilla chips at the very top. Shake and eat.
- Breakfast bento: Replace the chicken section with Greek yogurt and granola, keep the fruit section, and add sliced hard-boiled eggs and almonds. Done.
- Grain bowl bento: Use farro instead of quinoa and add roasted sweet potato cubes for a heartier fall version.
Make Ahead Tips
This entire system is built around one solid Sunday prep session:
- Grill all the chicken at once: Season and cook all 6 breasts in one batch. Slice, divide, and you’re done.
- Cook a double batch of quinoa: It reheats beautifully and keeps in the fridge for 5 days.
- Hard-boil a full 8 eggs: Use 4 for the bento boxes and keep the rest for quick snacks throughout the week.
- Prep all vegetables at once: Slice cucumbers, halve tomatoes, shred carrots, and chop romaine in one session. Store in separate containers.
- Assemble bento boxes and mason jars Sunday evening: Everything is ready to grab Monday through Thursday without thinking.
Total Sunday prep time: about 45–50 minutes. Time saved during the week: hours.

Meal Pairing Suggestions
- Bento box: Pairs well with a large water bottle and a piece of fruit for a complete desk lunch. Add a square of dark chocolate to the snack section for a little afternoon pick-me-up.
- Mason jar salad: Works as a standalone meal. Add a small container of hummus and a few crackers on the side if you want more calories.
- Both together for the week: Use the bento box Monday and Wednesday (heartier, more filling). Use the mason jar salad Tuesday and Thursday (lighter, quicker to eat). Keeps the week from feeling repetitive.
- Coffee pairing: Both pack well alongside a travel coffee cup — which is exactly the kind of morning that needs a meal this organized.
Leftovers and Storage
Grilled chicken (plain, unassembled):
- Refrigerator: airtight container, up to 4 days.
- Freezer: up to 3 months. Thaw overnight in the fridge.
Assembled bento boxes:
- Keep sealed in the fridge for up to 4 days.
- Don’t freeze assembled boxes — the fresh vegetables don’t hold up.
- Keep the spinach and tomato section undressed until eating day.
Mason jar salads:
- Sealed in the fridge for up to 4–5 days.
- Kale version lasts even longer — up to 6 days — because kale is sturdier than romaine.
- Do not freeze.
Cooked quinoa:
- Fridge: 5 days in a sealed container.
- Freezer: up to 2 months in a zip-lock bag. Thaw in the microwave with a splash of water.
FAQ
How many days in advance can I really make these? Bento boxes: 4 days safely. Mason jar salads: 4–5 days, with kale lasting up to 6. Both are genuinely fine all week if you meal prep Sunday. Day 5 is the limit — after that, quality starts to drop.
The quinoa in my bento got soggy by day three. What happened? Almost always comes down to one of two things: the quinoa wasn’t cooled completely before packing, or moisture from another section got into the quinoa area. Cool the quinoa fully on a sheet pan and make sure your container lid seals properly. A three-compartment container with a tight lid helps a lot.
Can I reheat the bento box? The chicken and quinoa sections reheat well — 90 seconds in the microwave. Transfer them to a microwave-safe dish first, since not all meal prep containers are microwave-safe (check the bottom of yours). Leave the snack section and spinach at room temperature.
My mason jar salad is soggy when I open it. Where did I go wrong? The layering order got reversed somewhere. Dressing must go at the very bottom, greens must go at the very top. If dressing is touching the lettuce before you shake it, the salad will be soggy by day two. Follow the layer order exactly.
Can I use rotisserie chicken instead of grilling? Yes, and it’s a great shortcut. Pull the chicken, season lightly with smoked paprika and garlic powder, and use it the same way. Saves the grilling step entirely.
Are these good for kids’ lunches too? The bento box absolutely is — swap the mixed nuts for raisins or crackers for younger kids, and cut the chicken into smaller pieces. The mason jar salad is more of an adult format, but the same ingredients can be packed flat in a container for kids.
I don’t have a 3-compartment container. Can I still make the bento box? Use small silicone cupcake liners inside a regular container to keep the sections separated. Works really well and costs almost nothing.
Wrapping Up
The difference between a good week and a chaotic one often comes down to whether you have real food ready to grab.
These two meals make that happen.
One Sunday prep session — about 45 minutes — and you’ve got lunches sorted Monday through Thursday. No scrambling, no sad fast food runs, no eating crackers at your desk because nothing was planned.
The bento box keeps you full and energized. The mason jar salad is crisp and fresh every single day. Both travel perfectly. Both actually taste good.
