I LOVE this side dish.  I love anything really to do with potatoes, but this recipe is a must.

Ingredients:

3 cups prepared mashed potatoes
1 can condensed cheddar cheese soup
1/3 cup sour cream
1/8 tsp ground black pepper
2 tbs diced green onions

Directions:

In a large bowl combine soup, sour cream, pepper, and onion.  Mix well.  Add in mashed potatoes stir until combined.  Spoon into a 1 1/2 quart baking dish.  Bake 350 degrees for 30 minutes.
