In a large skillet over medium heat, add the pound of ground beef. Cook until it’s nicely browned, about 5-7 minutes. Stir occasionally to break up the meat into smaller pieces.

Once the beef is browned, carefully drain any excess fat from the skillet. Add the chopped onions and bell peppers, and cook for about 3-4 minutes until they are tender.

Stir in the ketchup, brown sugar, apple cider vinegar, Worcestershire sauce, and garlic powder. Ensure everything is evenly incorporated.

Season the mixture with a pinch of salt and pepper to taste, and allow it to simmer on low heat for about 10-15 minutes so the flavors can blend together.

While the beef mixture simmers, prep your hamburger buns by toasting them lightly to avoid sogginess.

Finally, scoop generous portions of the beef mixture onto each toasted hamburger bun, serve warm, and enjoy!
