My absolute fave, and its super yummy and easy to make (especially using a Crockpot) :

GRAPE JELLY MEATBALLS

2 12 oz jars Heinz chili sauce
1 32 oz jar grape jelly
1 bag meatballs (about 80 in a bag)

Put chili sauce and jelly in a large pot, heat until jelly is melted and sauce is smooth, stirring often. Add frozen meatballs; heat until meatballs are thawed and then simmer for 3 hours.

Its sweet and spicy!
