1. Combine mince, Worcestershire sauce, garlic salt and pepper in a large bowl; mix well. Form 8, thin burgers. Each burger should be slightly larger than a slice of cheese.
2. Cut each slice of cheese into 4 equal pieces; stack the pieces. Sandwich one stack of cheese between 2 burgers. Tightly pinch edges together tightly seal the cheese within the meat. Repeat with the remaining cheese and burgers.
3. Preheat a cast-iron or other heavy bottomed frying pan over medium heat. Pan fry burgers until well browned, about 4 minutes. It is common for burgers to puff up due to steam from the melting cheese. Turn burgers and prick the top of each to allow steam to escape; cook until browned on the outside and no longer pink on the inside; about 4 minutes. Serve on burger buns.

Note

For the juiciest burgers, be sure your minced beef is at least 20% fat.

Note

Ensure you make a tight seal, because it needs to be TIGHT to avoid a cheesy eruption as the cheese melts, creates steam and tries to find its way out.
