Drizzle everything with olive oil and sprinkle with oregano, basil, salt, and pepper.
Toss all the ingredients together until evenly coated.
Cooking
Bake in the preheated oven for 25-30 minutes, or until the chicken is fully cooked and the vegetables are tender.
Garnish with fresh parsley before serving.
