In a large skillet, cook beef over medium heat until no longer pink; drain. Transfer to a 5-qt. slow cooker. Remove seeds from the chili peppers if desired; chop peppers. Add to the slow cooker. Stir in the beans, tomato paste, onion, green pepper, seasonings and 2 cups tomato juice.
Cover and cook on low for 4-6 hours or until heated through, adding more tomato juice if needed to achieve desired thickness.
Wear disposable gloves when cutting hot peppers; the oils can burn skin. Avoid touching your face.
