Preheat your oven to 400°F (200°C).
In a mixing bowl, combine chopped rosemary, minced garlic, lemon juice, olive oil, salt, and pepper.
Place the chicken breasts in the bowl and coat them well with the marinade.
Let the chicken marinate for at least 15 minutes for better flavor.
Prepare a baking tray with sliced zucchini, cherry tomatoes, and lime.
Place the marinated chicken breasts on top of the vegetables.
Spray with cooking spray for extra crispiness, if desired.
Bake in the preheated oven for 20-25 minutes until the chicken is cooked through.
Check the internal temperature; it should be 165°F (75°C).
Remove from the oven, let it rest for 5 minutes, and serve warm.
