In a large bowl, combine lean ground beef, breadcrumbs, ketchup, mustard, Worcestershire sauce, garlic powder, and onion powder. Mix thoroughly until well combined.

Divide the beef mixture into four equal portions and shape each into a compact patty about ¾ inch thick.

Heat about 2 tablespoons of avocado oil in a skillet over medium heat. Add the patties and cook for about 5-7 minutes on each side.

Whisk together the brown gravy mix and hot water in a separate bowl. Pour the gravy over the cooked patties.

Reduce heat to low and allow gravy to simmer over the patties for about 5 minutes before serving.
