Heat a large stock pot over medium-high heat.
Add ground beef and onions. Cook, breaking up beef with a spatula, until onions have softened and beef is no longer pink, about 5 minutes. Drain excess grease.
Add green pepper, beef broth, tomatoes, beans, corn, potato, chili powder, Worcestershire sauce, paprika, and cumin.
Bring to a boil; reduce heat and simmer for 40 minutes.
Season with salt and pepper.
Ladle into bowls and serve.
