You're more than welcome to try our recipe:
1 bag of meatballs from Walmart, or 1/2 bag from Costco
9oz BBQ sauce, whatever you prefer
9oz Grape jelly
Place it all in your slow cooker (4qt will hold it all), turn on low and let sit all day. You can do it in about 4 hours, but the longer they marinate, the better they taste.
