Twice-Baked Potatoes

4 large baking potatoes
1/3 cup margarine or butter
2/3 cup milk
2 tablespoons chopped onion
1/2 teaspoon salt
1/4 teaspoon pepper
Paprika

Directions:
Cut hot potatoes in half and scoop out the pulp, leaving a bit in the shell so that the shell does not collapse. Set the shells aside. In a large bowl, beat together potato pulp and margarine. Gradually beat in milk. Stir in onion, salt, and pepper. Spoon potato mixture into each shell. Arrange shells on baking sheet and sprinkle with grated cheese. Bake potatoes at 375° for 20-25 minutes or until completely heated through. Sprinkle with paprika and serve.
