Olive oil

1-1/2 pounds lean ground steak or use 1/2 lean beef and 1/2 ground pork

1 onion, chopped

2 stalks of celery, finely chopped

2 to 4 cloves garlic minced
1/4 cup chopped Italian Parsley

2 or more Tablespoons dried basil

1 tablespoon teaspoon dried oregano

Rosemary, and fennel seed (Optional)
Pinch of hot red pepper flakes

1/2 white wine
1/2 cup cream or milk (Optional)
1 cup beef or chicken broth

2 to 3 large cans chopped tomatoes

Salt and pepper

Optional: If you have a rind from a Parmesan cheese add it to the pot to simmer along with the sauce. Really enriches the sauce.

Saute chopped onions and celery in olive oil until softened.  Add
minced garlic and cook for 1 minute. Add the meat and saute until no
longer pink.

(Add cream/milk if using it and simmer until it has evaporated)   Add
1/2 cup white wine and simmer until wine has evaporated. Add the dried
herbs and fresh parsley. Coarsely puree tomatoes and add to the pot. 
Add chicken broth and simmer for at least 2 hours on low heat.

Serve over spaghetti with fresh grated Parmesan cheese.

NOTE:  You can also add the cream at the end rather than at the
beginning. Makes for a richer sauce.

The purpose of adding it early is that it is suppose to tenderize the
meat.
