Mix all ingredients (except cheese, sauce and buns) into bowl and make into four balls. Roll balls out to patties.
Place on hot grill. Cook on each side for 4 minutes or until desired.
When there is one minute left, toast hamburger buns with a thick slice of mozzarella on each. When finished spread a tablespoon of spaghetti sauce on bun and make into burger. Put sauce on side for dipping.
