Instructions: Mix all ingredients for meat balls together thoroughly, except the last, olive oil. Form into medium sized balls: brown in oil. Set aside and cook in tomato sauce later.

To make tomato sauce: Heat the oil: add onion, green pepper, garlic, mushrooms (drained and halved) and saute until golden. Stir in tomato paste; cook for 4 minutes. Press plum tomatoes through a strainer; add an equal amount of water. Combine with tomato paste mixture. Add sugar, salt and pepper. Bring to a boil; add meatballs and cook over low heat 1-1/2 hours or until sauce thickens slightly. Remove meatballs and put aside.

Cook tufoli in 6 quarts boiling, salted water for 12 to 15 minutes or until almost tender. Mash meat balls in a bowl. Add spinach (drained and finely chopped), salt, 2 tablespoons cheese and the egg, mixing well. Stuff this mixture into cooked tufoli. Cover bottom of a large casserole with half of sauce and arrange alternate layers of stufted tufoli and sauce, sprinkling each layer with cheese; finish with sauce. Cover dish and bake in a moderate oven (350 degrees) for 30 minutes. Serve with extra sauce and cheese.

Serves 6 very generously.
