If you have to take an appetizer, you won't go wrong with the dish. It is a crowd pleaser!!
3--8 oz packs of cream cheese (softened)
1 medium onion, chopped
2 cups--Parmesan Cheese
1/2 cup--Miracle Whip or Mayo
Pre-heat oven to 375*. Butter a 2-quart baking dish and set aside. Mix all ingredients together. Pour the mixture into the buttered dish and smooth out. Bake for 25-30 minutes or until golden brown. Serve warm with your favorite crackers (I highly recommend Wheat Thins).
