1 30 oz can refried beans
1 cup sour cream
1 packet Hidden Valley Ranch Dip mix
8 oz sharp cheddar cheese, shredded
Preheat oven to 350F.
Mix beans, sour cream, ranch mix, and half, about 1 cup, of the cheddar cheese together until it is combined then place it in a medium baking dish and cover with the remaining cheese. Make sure to use a fairly big dish (about 2 quart) because once you mix it all together it makes a pretty good amount.
Bake for 20 minutes, then remove from oven and serve warm with chips or as a side dish.
If you get in a big hurry, you can also microwave it for a minute, mix it up, and repeat until it it piping hot.
