Ginger Ale Meatballs

40 frozen, fully cooked meatballs (I used turkey ones)
2 cups ginger ale
2 cups ketchup
1 teaspoon minced garlic

Place frozen meatballs in a 3- to 4-quart slow cooker prepared with nonstick cooking spray. In a bowl, combine ginger ale, ketchup, and garlic. Pour mixture over meatballs. Cover and cook on low heat for 6-8 hours or on high heat for 3 hours. Serve with toothpicks as an appetizer, on hoagie buns, or over hot cooked noodles.
