Buy top round or London Broil steak, cut in large cubes and grind with the medium die. Make a white or brioche dough and form into hamburger buns. Bake until browned, cool slightly and cut in half horizontally. Form the beef into patties, season with salt, pepper and garlic powder. Broil over wood or charcoal until an internal temperature of 131° is reached. Dress the buns with mayonnaise, sliced tomato, a slice of sweet onion and pickle slices. Add the cooked patty and a slice of cheese. Close the sandwich and serve.
BTW, you can buy pre-baked and sliced buns, and formed burger patties to save some time.
