Preheat your oven to 400°F (200°C) and line a large sheet pan with parchment paper for easy cleanup.
Chop the red bell pepper and red onion into 1-inch chunks and break the broccoli into bite-sized florets.
Mince the garlic clove finely.
Place the chicken breast on one side of the sheet pan and arrange the chopped vegetables on the other side.
Drizzle the extra virgin olive oil over both the chicken and the vegetables.
Evenly sprinkle the dried rosemary, dried thyme, sea salt, black pepper, and minced garlic over everything.
Toss the vegetables with your hands or a spatula to coat them thoroughly in the oil and spices, then rub the seasoning into the chicken.
Spread the ingredients out into a single layer to ensure even roasting.
Roast in the center of the oven for 20 to 25 minutes, or until the chicken reaches an internal temperature of 165°F and the vegetables are tender with slightly charred edges.
Remove from the oven and let the chicken rest for 5 minutes before slicing it into strips.
Serve the sliced chicken alongside the roasted vegetables for a clean and nutrient-dense meal.
