Liz's spaghetti sauce Recipe

Brown ground beef and onions in shortening. Drain off excess shortening. Add spaghetti mix, chili powder, red pepper, cayenne, garlic salt, onion salt, oregano, salt, pepper, stewed tomatoes and tomato sauce. Bring to a boil and simmer from 45 minutes to 1 hour. Stir often to prevent sticking. Add a little water if becomes too thick. Serve over long spaghetti cooked to directions on package. Sprinkle with parmesan cheese, if desired.
