I got this easy recipe from my friend Jeri. Good as meatball sandwich.
2 lbs frozen cooked meatballs, thawed.
2 bottles (18 oz each) barbecue sauce. For one bottle use Famous Dave’s barbecue sauce and for the other bottle use Sweet Baby Ray’s barbecue sauce.
In medium bowl, mix barbecue sauce, mixing well. Pour on top of meatballs in slow cooker; stir to coat.
Cover; cook on High heat setting 2 1/2 to 3 hours or until thermometer inserted in center of meatball reads 165°F. Stir before serving to evenly coat meatballs in barbecue sauce mixture.
