Combine ground beef, finely chopped mushrooms, garlic, Worcestershire sauce, salts, pepper, and egg in a large bowl. Mix well until incorporated, but don't overwork the meat (the burgers will be tough otherwise.)
Divide the mixture into 6 equally sized portions. Form 5-inch wide patties from each portion, each one about the same dimensions as a slice of bread.
Place 1/3 of the shredded cheese in the center of a patty, then top it with a second patty. Tightly pinch the edges together to seal the cheese within the meat. Cup each patty with your hands to round out the edges, and press on the top with your palm to flatten it into a single thick patty. Transfer to a plate. Repeat with the remaining cheese and patties. Refrigerate for at least 30 minutes.
While the burgers chill, cook your grilled cheese "buns". Preheat a large nonstick skillet over medium-low heat.
Spread butter onto one side of each slice of bread. Place a slice of bread, buttered side down, on the skillet, then top with a slice (or two!) of cheese. Top with a second slice of bread, butter side-up.
Working in batches, cook each sandwich, flipping once, until the bread is golden brown (not burned!) on each side and the cheese is just starting melt. Transfer finished sandwiches to a plate and wipe the skillet clean.
Remove the burgers from the refrigerator and season the outsides to taste with salt. Cook burgers until well browned, about 3-4 minutes on each side, to desired doneness. Do not press on the burgers as they cook if they puff up - use a fork to poke the beef and release the steam caused by the melting cheese. When the burgers are done, let them rest on a paper towel-lined plate for at least 5 minutes before serving.
Place each patty on one grilled cheese, top with your favorite toppings, then crown it with another grilled cheese. Keep it all together using a burger knife or skewer.
