Follow these simple instructions to create your Mediterranean Chicken Zucchini Bake:

1. Preheat Oven: Preheat your oven to 375°F (190°C).
2. Prepare Chicken: Season chicken breasts with salt, pepper, oregano, and basil in a large mixing bowl.
3. Sauté Vegetables: In a large skillet, heat olive oil over medium heat. Add garlic and onion, cooking until fragrant (about 2 minutes).
4. Add Remaining Vegetables: To the skillet, add sliced zucchinis, bell peppers, and cherry tomatoes. Sauté for 5-7 minutes until slightly softened.
5. Combine: In a large baking dish, layer the vegetables on the bottom, then place the seasoned chicken on top.
6. Bake: Cover the baking dish with foil and bake in the preheated oven for 25 minutes.
7. Add Cheese: Remove the foil and sprinkle crumbled feta cheese over the chicken and vegetables. Bake uncovered for an additional 10-15 minutes, or until the chicken is cooked through (internal temperature should reach 165°F or 75°C).
8. Garnish: Once baked, remove the dish from the oven and let it rest for a few minutes. Garnish with fresh parsley before serving.

With these straightforward steps, you’ll create a delightful Mediterranean meal that showcases flavor and health in every bite.
