Preheat your oven to 400°F (200°C) and line a large rimmed baking sheet with parchment paper.
Cut the chicken breast into one-inch bite-sized pieces and place them into a large mixing bowl.
Add the broccoli florets, sliced carrots, and bell peppers to the bowl with the chicken pieces.
Drizzle the extra virgin olive oil over the chicken and vegetables, then sprinkle in the minced garlic, rosemary, thyme, sea salt, and black pepper.
Toss the mixture thoroughly until every piece of chicken and vegetable is evenly coated in the oil and herb seasoning.
Spread the ingredients in a single layer across the prepared baking sheet, ensuring they are not overcrowded so they roast rather than steam.
Place the sheet in the oven and roast for 20 to 25 minutes, or until the chicken is cooked through and the vegetables are tender with slightly browned edges.
Remove from the oven and let the dish rest for a few minutes before serving to allow the juices to redistribute.
