Preheat your oven to 400°F (200°C) and line a large rimmed baking sheet with parchment paper for easy cleanup.
Cut the chicken breast into 1-inch bite-sized cubes and slice the carrots into thin rounds.
De-seed the red bell pepper and chop it into 1-inch pieces, then mince the garlic clove finely.
In a large mixing bowl, combine the chicken cubes, broccoli florets, bell pepper, and carrots.
Drizzle the extra virgin olive oil over the mixture and sprinkle with dried rosemary, dried thyme, sea salt, black pepper, and minced garlic.
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 baking sheet, ensuring the pieces aren't too crowded so they roast rather than steam.
Roast in the center of the oven for 20 to 25 minutes, or until the chicken is cooked through and the vegetables are tender and slightly caramelized at the edges.
Remove from the oven and let rest for 2 minutes before serving warm.
