Cheese-Stuffed Burgers

Combine ground beef, Worcestershire sauce, black pepper, and garlic salt in a bowl until they are fully incorporated. Divide the mixture into eight portions and shape each one into an oval patty, slightly thicker than a standard cheese slice.

Arrange all the cheese slices in a stack and cut them into four equal squares. Place one small square of cheese in the center of each beef patty, cover it with another patty, and press the edges together firmly to seal the cheese inside. Make sure the seals are tight to prevent the cheese from escaping during cooking. Repeat this process with the remaining cheese and patties.

Preheat a large cast-iron skillet over medium heat. Cook the beef patties in the hot skillet until they are nicely browned, taking about 4 minutes; as a result of the cheese melting, they will puff up. Flip the patties over and use a fork to prick the tops, allowing any steam to escape before cooking for another 4 minutes or until they are browned on the other side and cooked through; an instant-read thermometer inserted into the center should read at least 160 degrees F (70 degrees C).

Serve the cooked patties on hamburger buns.
