In a small bowl, mix olive oil, minced garlic, lemon zest, lemon juice, oregano, paprika, salt, and pepper to create a marinade.
Place the chicken breasts in a large resealable bag or glass dish, and pour the marinade over the chicken. Seal the bag or cover the dish and marinate in the refrigerator for at least 30 minutes (up to 2 hours for more flavor).
While the chicken is marinating, preheat your oven to 400°F (200°C).
Line a baking sheet with parchment paper. Remove the chicken from the marinade and place it on the prepared sheet.
Scatter the broccoli florets and halved cherry tomatoes around the chicken on the baking sheet. Drizzle with a bit of olive oil and season with salt and pepper.
Bake in the preheated oven for 20-25 minutes, or until the chicken is cooked through and registers an internal temperature of 165°F (75°C).
While the chicken is baking, prepare the quinoa according to package instructions (typically boiling in water for about 15 minutes).
Once everything is cooked, allow the chicken to rest for a few minutes, then slice it into strips.
To assemble your meal prep containers, divide the cooked quinoa among 4 containers, then top with sliced chicken, roasted broccoli, and cherry tomatoes. Garnish with fresh parsley.
Allow the containers to cool before sealing and refrigerating.
Notes
Marinate the chicken for longer for enhanced flavor.
