Classic Marinara Sauce

Here is another tomato sauce recipe.  I will most likely use sweet sausage here.  Some of my family members are not as fond of the hot sausage as I am. 

1/2lb. ground beef
1/4lb. Italian sausage
1/2 C. onion, chopped
1 clove garlic, minced
1 16oz. can chopped tomatoes
1 16oz. can tomato sauce
10 button mushrooms, chopped
1/2 C. green pepper, chopped
1 bay leaf
1/2 tsp. oregano
1/4 tsp. basil
1/8 tsp. pepper
 salt to taste
cooked spaghetti

In skillet, cook the ground beef, sausage, onion and garlic until the meat is brown and onion is tender; drain off the fat.  In a crockpot, combine the tomatoes, tomato sauce, mushrooms, green pepper, bay leaf, oregano, basil, pepper, and salt.  Stir in the meat mixture.  Cover; cook on low for 10 to 12 hours or on high for 5 to 6 hours.  Remove bay leaf and serve over hot spaghetti.
