1/4 cup chopped onion

15 oz. can spaghetti sauce with mushrooms

6 oz. spaghetti

2 tablespoons grated parmesan cheese (opt.)

Brown hamburger and onions and then drain.  Add spaghetti sauce and simmer 10 minutes.  Break spaghetti into thirds and cook according to package directions.  Rinse and drain.  Mix spaghetti and sauce.

Melt butter in saucepan. Stir in flour and salt.  Slowly add milk and water. (This is like making gravy.)  Stir constantly until thick.  Add 1/2 of the shredded cheese and parmesan cheese.  Stir until melted.
