Mix ingredients together in a bowl. Preheat oven to 300 degrees. Measure out 2 tablespoons of mixture for each meatball and roll into a ball with your hands. Spray cooking sheet and place meatballs on it. Place into oven and cook 15 minutes on one side and roll over and cook 15 minutes on the other side. After they are out of the oven, let stand for about 10 minutes to allow them to firm up.
