In a large pot, brown the steak on high heat.
Turn down to medium-high, add the onion, pepper, and olive oil, and cook for about 2-3 minutes, or until the onions and peppers start to brown.
Sprinkle the Worcestershire sauce, mustard, cumin, garlic powder, chili powder, and oregano over the mixture, and cook for 2-4 minutes.
Reduce the heat to medium, add the crushed tomatoes, kidney beans, beef broth, salt, and pepper, and cook for 5 minutes.*
Remove from the stove, sprinkle with cheese, serve, and enjoy!
