Creating the Mediterranean Chicken Sheet Pan Dinner is straightforward if you follow these simple steps:

1. Preheat the Oven: Preheat your oven to 400°F (200°C).
2. Prepare Marinade: In a bowl, whisk together olive oil, minced garlic, lemon juice, oregano, thyme, salt, and pepper.
3. Marinate the Chicken: Place the chicken breasts in a resealable bag or bowl. Pour the marinade over the chicken, ensuring it’s well-coated. Let it marinate for at least 30 minutes.
4. Prepare Vegetables: While the chicken marinates, prepare the vegetables by slicing the bell peppers, onion, zucchini, and halving the cherry tomatoes.
5. Arrange on Sheet Pan: On a large sheet pan, arrange the marinated chicken breasts in the center. Surround them with the prepared vegetables.
6. Drizzle with Remaining Marinade: Drizzle any remaining marinade over the vegetables for added flavor.
7. Bake: Place the sheet pan in the preheated oven and bake for 30-35 minutes, or until the chicken is cooked through and the vegetables are tender.
8. Check for Doneness: Ensure the chicken reaches an internal temperature of 165°F (75°C).
9. Garnish: Once cooked, remove the pan from the oven. Garnish with fresh parsley and crumbled feta cheese if desired.
10. Serve: Allow the dish to cool slightly before serving.
