Preheat your oven to 400°F (200°C) and line a large sheet pan with parchment paper.
Chop the chicken breast into 1-inch bite-sized pieces and place them in a large mixing bowl.
Cut the broccoli into small florets, slice the bell pepper into strips, and coin the carrots.
Add the vegetables to the bowl with the chicken, then drizzle with extra virgin olive oil.
Mince the garlic and add it to the bowl along with the rosemary, thyme, sea salt, and black pepper.
Toss everything thoroughly until the chicken and vegetables are evenly coated in the oil and spices.
Spread the mixture in a single layer on the prepared sheet pan, ensuring nothing is overcrowded.
Roast for 18-22 minutes, or until the chicken is cooked through and the vegetables are tender and slightly caramelized.
Remove from the oven and let rest for 2 minutes before serving.
