Preheat your oven to 400°F (200°C) and line a large sheet pan with parchment paper. Chop your bell peppers, zucchini, red onion, and carrots into bite-sized pieces.

In a large mixing bowl, combine chopped vegetables with olive oil, garlic powder, dried Italian herbs, salt, and pepper. Toss until evenly coated.

Place the seasoned vegetables on one half of the sheet pan and arrange chicken on the other half.

Slide the sheet pan into the oven and roast for about 25-30 minutes, checking that the chicken reaches an internal temperature of 165°F (75°C).

Remove from oven, let rest for a few minutes, then serve and enjoy!
