10 potatoes, peeled and cut into chunks
2 (8 ounce) packages, shredded cheddar cheese
1 stick (1/2 cup) margarine
½ cup milk
2 teaspoons salt
Bring potatoes to boil over a high heat; reduce and simmer until soft, about ½ hour. Remove from heat, drain and add ¾ package cheddar cheese, margarine, milk and salt to the pot. Mash until almost no lumps remain. Pour mixture into 9 x 13-inch baking dish. Preheat oven to 350 degrees. Sprinkle remaining cheese on top of potatoes. Bake for about 45 minutes.
