This is very close to the recipe that we use, which is really good IMO. You can tweak the amount of hot sauce, Ranch and cheese that you use to suit taste. Seems to me that we use either a can of "Cream of chicken" or "cream of Mushroom", but I can't recall if we do or not.
8 oz. pkg. cream cheese, softened
1/2 cup ranch salad dressing (Hidden Valley my fav)
1/2 cup (or to taste) of Red Hot sauce or Buffalo sauce. (I like Franks Red-Hot)
1/2 cup shredded mozzarella cheese
2 cans (12.5 oz. each) Chunk Chicken Breast in Water, or cook and shred your own chicken breasts
DIRECTIONS:
HEAT oven to 350°F. Place cream cheese into deep baking dish. Stir until smooth.
MIX in salad dressing, hot or buffalo sause and cheese. Stir in chicken.
BAKE 20 min. or until mixture is heated through; stir. Garnish as desired. Serve with crackers, tortilla chips or vegetables.
