I simply substitute the same amount of Greek yogurt for the amount of sour cream a recipe or package callsfor ie. 1 cup usually per package will do. I cut it down to 3/4 and add milk or light cream for a dressing. Sometimes that's too thick for some people so mix it slowly and carefully to get the consistency you want without losing any of the flavor. I've also tried covering chicken pieces with the dip and then panko bread crumbs mixed with a little partisan cheese, onion seasoning and about a half package of the dip dry, and then frying the pieces up, yummy! Chicken pieces with flavor, you don't need a sauce to go with them.

sounds yummy!  Thank you for sharing the recipe!
