I tried my meatballs in the grape jelly and ketchup sauce! Yummy!
I did 1 cup grape jelly and 1 cup ketchup and a dash of Worcestershire sauce placed over meatballs in slow cooker for 3-4 hours on low (meatballs were already cooked).
It was very good but could have been a little less sweet. So next time I think I'll cut the grape jelly in half.
