Preheat your oven to 400°F (200°C) and line a large baking sheet with parchment paper.
Chop the zucchini into half-moons and the red bell pepper into bite-sized chunks. Mince the garlic cloves.
Place the chicken breast on one side of the baking sheet and the zucchini, peppers, and cherry tomatoes on the other side.
In a small bowl, whisk together the olive oil, lemon juice, minced garlic, rosemary, thyme, sea salt, and black pepper.
Drizzle the herb oil mixture over both the chicken and the vegetables, tossing the vegetables to ensure they are evenly coated.
Roast in the oven for 20-25 minutes, or until the chicken reaches an internal temperature of 165°F and the vegetables are tender and slightly charred.
Remove from the oven and let the chicken rest for 5 minutes before slicing to keep it juicy.
Serve the sliced chicken alongside the roasted garden vegetables for a clean and satisfying meal.
