Cold boiled potatoes, 1 quart,
Butter, 1 tablespoon,
Salt, 1/2 teaspoon,
Pepper, 1/2 teaspoon,
White onion, 1,
Parsley, 1 tablespoon (chopped fine).
Peel and cut the potatoes into inch cubes. Put a tablespoon of butter in the frying-pan, and when hot add the onion, minced fine, and cook until soft, but not brown. Then add the potatoes and toss them with a fork until they are of an even color.
Sprinkle the salt, pepper, and parsley over them, and again stir with the fork.
Serve at once, with broiled steak.
