The simplest lunch box: chicken breast and raw veggies. Low calorie, high protein, zero excuses for skipping meal prep.
Pat chicken breasts dry and season both sides evenly with salt and black pepper.
Heat a nonstick skillet over medium-high heat, add olive oil, and place chicken in the hot pan.
Cook chicken for 4–5 minutes per side without moving to allow for even browning and juiciness.
Remove chicken to a plate, cover loosely with foil, and let rest for 3 minutes before slicing into strips.
Assemble each lunch box: arrange carrot, cucumber, red bell pepper, and celery sticks neatly, and add sliced chicken.
Drizzle lemon juice over veggies and chicken right before sealing to boost freshness.
