In a large saucepan, cook the beef, onion, peppers and garlic over medium heat until meat is no longer pink; drain. Add the remaining ingredients. Simmer, uncovered, for 5 minutes or until cheese is melted (do not boil).
Editor's Note: When cutting hot peppers, disposable gloves are recommended. Avoid touching your face. For a tasty taco salad, serve Cheesy Taco Chili on a bed of lettuce. Sprinkle with shredded cheese and chopped tomatoes; top with sour cream and French or Russian salad dressing.
Wear disposable gloves when cutting hot peppers; the oils can burn skin. Avoid touching your face.
