1 pkg. spaghetti noodles (I use extra thin noodles)
1 lb. hamburger
1 jar spaghetti sauce, your choice
1 (2 c.) pkg. Mozzarella cheese
1 med. onion (optional)
Parmesan cheese (green can)

Brown the ground hamburger and add 1 medium chopped onion, drain grease. Add spaghetti sauce and seasonings. Boil noodles in salted water; drain. In a 9 x 13 inch pan, spread out spaghetti noodles, sprinkle Mozzarella over spaghetti noodles, then pour spaghetti sauce over noodle/cheese mixture. Sprinkle grated Parmesan cheese over the top. Bake in oven at 300 degrees for about 20 to 30 minutes until cheese melts. Serve. Serves 4 to 6 people (depending on your appetite).
