Pre-heat oven to 450 degrees and line a baking sheet with foil. Spray with cooking spray.
Scatter all the vegetables and garlic cloves on the prepared baking pan and drizzle with olive oil, salt, pepper, fresh herbs and chili flakes. Toss well then bake 35-40 minutes or until golden brown and caramelized. Garnish with additional fresh herbs if you wish before serving.
