Directions

1. Cook ground beef with onion and bell pepper in a large frying pan over medium-high heat, stirring occasionally, until beef is browned and vegetables are tender, about 8 minutes. Drain mixture and return to the pan.
2. In a small bowl, stir together ketchup, brown sugar if using, Worcestershire sauce, vinegar, mustard, and garlic powder. Add to the ground beef mixture and cook, stirring often, until warmed through, about 2 minutes.
3. Open up hamburger buns onto plates. Top bottom of buns with sloppy Joe mixture and top with pickles. Set hamburger bun tops in place.
