1 lb. hamburger
1 med. onion, chopped
1 sm. can tomato sauce
1/2 tsp. garlic salt
1/4 tsp. salt
1/4 tsp. pepper
1 tsp. oregano
1 pkg. Mozzarella cheese (3 c. size)
1 pkg. 8 lg. or 12 sm. hamburger buns

Heat oven to 375 degrees. Brown hamburger and chopped onion. In small bowl combine tomato sauce, garlic salt, salt, pepper and oregano. Mix well.

Spoon hamburger on bun, spoon about 1 1/2 tablespoons sauce over top of hamburger. Sprinkle Mozzarella cheese on top and wrap in foil. I usually place 2 in one package. Place on cookie sheet and heat for approximately 20 minutes.
