01 - Preheat the oven to 400°F. Line a large baking sheet with parchment paper.
02 - In a bowl, toss chicken breasts with olive oil, smoked paprika, garlic powder, oregano, salt, and black pepper.
03 - Place the seasoned chicken on one side of the prepared baking sheet.
04 - In a separate bowl, toss bell peppers, red onion, zucchini, and cherry tomatoes with olive oil, dried thyme, salt, and black pepper. Spread evenly on the opposite side of the baking sheet.
05 - Roast in the oven for 25 to 30 minutes until the chicken reaches an internal temperature of 165°F and vegetables are tender and caramelized. Let the chicken rest for 5 minutes before slicing.
06 - While roasting, combine quinoa, water, and salt in a medium saucepan. Bring to a boil, reduce heat to low, cover, and simmer for 15 minutes. Remove from heat and let sit, covered, for 5 minutes, then fluff with a fork.
07 - Divide the quinoa evenly among four containers. Top with sliced chicken and roasted vegetables. Garnish with fresh parsley and lemon wedges.
08 - Allow bowls to cool before sealing. Store in the refrigerator for up to four days.
