In Dutch oven, fry bacon until crisp. Remove; reserve. Add beef and onion to bacon fat and sauté until well browned. Add the tomato juice and chili seasoning mix; bring to boil. Reduce heat and simmer, covered, stirring occasionally, 1 hour, or until beef is tender. Add kidney beans, simmer 15 minutes longer. Meanwhile, cook macaroni as package directs; drain. Stir into beef mixture with bacon. Sprinkle with cheese. Broil 4 inches from heat until cheese melts.
