Start your Grill on 'smoke' with the lid open until a fire is established in the burn pot (3-7 minutes). Preheat to 400F. Place all ingredients in a bowl, combine them and stir well. Shape the mixture into 30 meatballs (1 ½ inches in width). Spray a broiler pan with cooking spray, place on the grill, and bake for 15 minutes until fully cooked and browned. Remove from grill, cool for 5 minutes, and serve.
