Preheat oven to 450°. Process first 3 ingredients in a food processor 10 to 15 seconds or until finely ground. Stir together breadcrumb mixture and cheese in a medium bowl. Toss zucchini rounds with oil. Dredge zucchini, 1 round at time, in breadcrumb mixture, pressing gently to adhere. Place rounds in a single layer in a jelly-roll pan coated with cooking spray. Bake 30 minutes or until browned and crisp. Serve hot.
