I know what you're thinking... grape jelly? Oh, yeah! This recipe is one of those crazy concoctions that is so delicious no on will believe what's in it! Make 'em guess! Kids absolutely love these meatballs because the sweetness of the jelly, and the ketchup too, counteracts the chili sauce to make it taste a little milder. This makes a great appetizer or a fun Sunday supper in front of the TV for movie night. Enjoy!
