1/4 cup grated Parmesan, Parmigiano-Reggiano or Romano cheese
2 cloves garlic, chopped

1 small onion, finely chopped
1 cup beef stock, available on soup aisle in market in small paper boxes

A handful chopped flat-leaf parsley
10 leaves fresh basil leaves, torn or thinly sliced
Grated cheese, such as Parmigiano-Reggiano or Romano, for passing at table
Crusty bread or garlic bread, for passing at the table

Cooking Recipe:

Preheat oven to 425 degrees F.

Place a large pot of water on to boil for spaghetti. When it boils, add salt and pasta and cook to al dente.

Mix beef and Worcestershire, egg, bread crumbs, cheese, garlic, salt and pepper. Roll meat into 1 1/2 inch medium-sized meatballs and place on nonstick cookie sheet or a cookie sheet greased with extra-virgin (measure of purity, virgin is less, extra-virgin is purer) olive oil. Bake balls 10 to 12 minutes, until no longer pink.

Heat a deep skillet or medium pot over moderate heat. Add oil, crushed pepper, garlic and finely chopped onion. Saute 5 to 7 minutes, until onion bits are soft. Add beef stock, crushed (as in squashed, mashed, beat into small bits) tomatoes, and herbs. Bring to a simmer and cook for about 10 minutes.

Toss hot, drained pasta with a few ladles of the sauce and grated cheese. Turn meatballs in remaining sauce. Place pasta on dinner plates and top with meatballs and sauce and extra grated cheese. Serve with bread or garlic bread.
