Sweet and Spicy Meatballs

This isn't much of a recipe, but the flavor is so yummy and unique.  I brought them to a Super Bowl party along with this pasta salad and this caramel apple dip, and they were a huge hit.  We had the leftovers in toasted rolls with melted provolone, spinach, onions, and peppers, and they were fabulous too. 

1 jar grape jelly
1 jar salsa (I used Pace Picante-medium)
1/2 bag frozen meatballs (I used the Italian-style ones from Costco)

Mix equal parts grape jelly and salsa, then pour over meatballs in the crockpot.  Cook 4-6 hours, or until jelly has melted into sauce and meatballs are heated through.
