My family has a variation of this dip at every holiday gathering. We omit the mushrooms in lieu of green peppers, add 1 cup sour cream, onion flakes and garlic powder (just 1/2- 1 tsp. of each according to preference) and reduce the milk in the recipe to 4 Tbsp and skip the parsley. I heat mine in the microwave in my mini crockpot insert and then keep it hot that way. I serve mine with Wheat Thins (any variety).
