Coat a large skillet with cooking spray. Cook ground beef and onion over medium-high heat until meat is browned, about 10 minutes; drain off fat.
Stir in undrained stewed tomatoes including juice, tomato juice, chili peppers and chili powder; bring mixture to a boil.
Stir in macaroni and beans; return to boiling. Reduce heat, cover and simmer until macaroni is tender, about 15 minutes. Spoon chili into bowls and sprinkle with cheese. Yields about 1 cup of chili and 1 tablespoon of cheese per serving.
