One year my dh picked up some BBQ Dip while on a Milk run to the store, It was really yummy, but damn expensive for a little tiny container. All you have to do is take 1 container of sour cream and 1/4-1/2 cup of your favorite BBQ sauce.
Blend well. Easy, Cheap and yummy on chips, crackers and believe it or not, carrot sticks.
