Place meatballs in a 3- to 4 1/2-quart slow cooker that has been prepared with nonstick cooking spray. In a bowl, combine the remaining ingredients. Pour sauce over meatballs. Cover and cook on low heat for 4-6 hours, or until meatballs are heated through. Serve as an appetizer with toothpicks or over rice as a main dish. Makes 10-12 servings.
Variation: Combine all ingredients in a 3- to 4-quart saucepan. Cover and simmer over medium-low heat on the stove for 55-60 minutes, stirring occasionally until meatballs are heated through.
