Funeral Potatoes

15 1/2 ounces cream soup (I use one chicken and one celery soup)
1/2 teaspoon melted butter
2/3 (15 1/2 ounce) can water (use soup can)
8 ounces Cheez Whiz (Jalapeno Cheez Whiz is good, too)
8 ounces sour cream
salt and pepper
6 cups potatoes, cooked

Combine all ingredients and mix with:.
6 cups diced cooked potatoes (Use 6-8 baked potatoes, or 2 lbs frozen diced potatoes).
Mix 2 cups bread crumbs (or crush corn flakes or potato chips) with another 1/2 cube melted butter. Sprinkle on top of potatoes and bake for 45 minutes at 350.
