Italian Spaghetti
Ingredients
Directions
Boil spaghetti in salted water until tender, with the onion stuck with 2 cloves.
Strain and rinse with cold water.
In a saucepan, combine strained tomato juice, butter, and thickening to make a tomato sauce, then add the mushrooms.
In a buttered pan, layer the spaghetti and sauce, and sprinkle with grated cheese.
Bake until heated through.
