1 med. potato, diced
1/4 c. green peppers, chopped
1/4 c. chopped mushrooms, canned or fresh
2-3 tbsp. butter
Square of foil
1/4 c. chopped onion

Place diced potato on square of foil. Top with onion, pepper, mushrooms and butter. Fold foil over potato; close ends and top so butter will not drip out into oven. Bake at 350 degrees for 35 to 45 minutes or until potato tests done. You may want to add salt, pepper, sour cream, cheese or any other of your favorite toppings.
