In a saucepan, brown the ground meat, stirring to break it up as it cooks. Transfer browned meat to a colander to drain excess fat. Return browned meat to the pan and add tomato sauce. Bring to a boil, cover, then turn down the heat to low and simmer for about 15 to 20 minutes.

Cook the spaghetti according to package directions. Strain. Place spaghetti in a pasta bowl and top with meat sauce and parmesan cheese. Serve with a simple green salad and bread on the side.
