Add the onion, bell pepper, and garlic; cook until the onion is translucent.
Transfer the meat mixture to a 6-quart slow cooker.
Add the beans, tomatoes, tomato paste, tomato sauce, Worcestershire sauce, beef broth, and hot sauce.
Stir in the chili powder, cumin, paprika, cayenne, salt, pepper, and sugar.
Cover and cook on low for 4 to 6 hours or high for 2 to 3 hours, stirring occasionally.
Serve with shredded cheese, sour cream, corn chips, or tortilla chips.
