In a large bowl, combine 1-1/2 teaspoons of fresh thyme (or 1/2 teaspoon dried), water, garlic salt, oregano, paprika and pepper. Add beef; mix well. Shape into four to six patties. Coat patties with flour; dip into egg and then crumbs. In a skillet, brown patties in butter. Arrange in a greased shallow baking dish. Pour half of the spaghetti sauce over patties. Sprinkle with cheeses; top with remaining sauce. Bake at 400° for 25 minutes or until meat is no longer pink. Sprinkle with remaining thyme. Serve patties and sauce on buns if desired.
