I peel about 7 or 8 med size potatoes and slice them. Put them in a 13 x 9 casserole dish. Open a can of cream of mushroom soup and put in bowl. Fill the soup can 1/2 of milk and pour in bowl and mix together, then pour over potatoes. Slice Velvetta cheese and place on top of that. Bake at 350 for about 45 mins with foil on top. Remove foil and finish baking until golden brown. Yummy!
