Preheat your oven to 400°F (200°C) and line a large sheet pan with parchment paper for easy cleanup.
Cut the chicken breast into bite-sized 1-inch cubes and slice the carrot into thin rounds.
Chop the red bell pepper into 1-inch pieces and break the broccoli into small, uniform florets.
Mince the garlic cloves and finely chop the fresh rosemary and thyme leaves.
In a large mixing bowl, combine the chicken, broccoli, peppers, and carrots.
Drizzle with extra virgin olive oil and add the minced garlic, rosemary, thyme, sea salt, and black pepper.
Toss everything thoroughly until the chicken and vegetables are evenly coated in the oil and herbs.
Spread the mixture in a single layer on the prepared sheet pan, ensuring nothing is overcrowded so it roasts rather than steams.
Roast in the oven for 20 to 25 minutes, tossing halfway through, until the chicken is cooked through and the vegetables are tender with charred edges.
Remove from the oven and serve immediately while hot.
