1 onion, chopped
2 c. ketchup
1/2 c. grape jelly
1 t. garlic powder
1/2 t. onion powder
1-2 T. Worcestershire sauce
1/4 c. dark brown sugar
3-14 oz. bags frozen meatballs
Add all ingredients except meatballs to large crock pot.
Stir well. The jelly will still be clumpy, but will melt down into the sauce as it cooks.
Add in the meatballs and stir to coat.
I have a programmable crock pot so I set mine to cook on low for 3 hours and then it switches to warm. These are great as appetizers but my kids LOVE them shoved in hot dog buns... yum.
