In a large skillet; add the ground beef, green bell pepper, and onion. Simmer over medium-heat until the ground beef has cooked.
Mix in the crushed tomatoes, ketchup, and worchestire sauce. Simmer over medium-to-low heat for at least 20 minutes to allow the flavors to blend together. If you are able to allow it to simmer longer, the better. Taste and season with taste and pepper.
Serve with fresh vegetables on the side or on top of a roll.
Store leftovers in an airtight container in the refrigerator up to 5 days.
