Step 1: Preheat Oven: Preheat oven to 400F (200C). Line a large baking sheet with parchment paper for easy cleanup.
Step 2: Prepare Vegetables: In a large bowl, combine the sliced bell peppers, zucchini, red onion, and halved cherry tomatoes. Add the minced garlic.
Step 3: Season Vegetables: Drizzle the vegetables with olive oil and lemon juice. Sprinkle with oregano, basil, salt, and pepper. Toss well to ensure the vegetables are evenly coated with the seasoning.
Step 4: Arrange on Baking Sheet: Spread the seasoned vegetables in a single layer on the prepared baking sheet.
Step 5: Prepare Chicken: Place the chicken breasts on top of the vegetables on the baking sheet. Lightly drizzle the chicken breasts with a bit more olive oil and sprinkle with a pinch of salt and pepper.
Step 6: Bake: Bake in the preheated oven for 20-25 minutes, or until the chicken is cooked through and the vegetables are tender. The internal temperature of the chicken should reach 165F (74C).
Step 7: Serve: Remove from the oven and let rest for a few minutes. If desired, sprinkle with crumbled feta cheese and fresh parsley before serving.
Tips and Substitutions:
For a spicier dish, add a pinch of red pepper flakes to the vegetables. Other vegetables like broccoli florets, asparagus, or mushrooms can be substituted based on preference and seasonal availability. To make it dairy-free, simply omit the feta cheese. For a richer flavor, use a high-quality extra virgin olive oil.
