CHEESY POTATOES

There are two versions of these potatoes. At the blue house, we use the hash browns. Please go to the brown house where we use real potatoes and spend our days peeling.

2 pounds frozen hash brown potatoes
1 can cream of mushroom soup
1 16-ounce container sour cream
2 cups shredded cheddar cheese
l/2 cups margarine or butter
green onions
salt and pepper
