In a medium sized pot, cook the ground beef until browned thoroughly
While the beef is cooking, use a sharp knife on a cutting board and dice the onion and green pepper
Add the diced onion and pepper to the browned ground beef and stir until combined
Add ketchup and brown sugar. Stirring occasionally to make sure the beef does not stick to the bottom of the pot
Simmer on low heat for 15-20 minutes, until the flavors have all melded together. *Think of this like chili, the longer it cooks, the better it tastes!
