In a large bowl, add beef, worcestershire sauce, soy sauce, fish sauce, salt, and pepper.
Use your hands to mix until the mixture is just combined. You don’t want to overwork the beef.
Divide ground beef into 4 equal portions (don’t flatten them out yet).
Heat a large skillet over medium high heat (about 350 degrees F).
Once hot, melt 1 tablespoon butter.
Add in 2 of the patties and smash flat with a spatula until they’re about 1/2 inch thick.
Cook for 2 minutes, then flip.
Cook for an additional 2 minutes, or until the patties are cooked to your liking. In the last 30 seconds of cook time, top each patty with a slice of cheese, and cover the pan with a lid to melt the cheese.
Remove from pan and repeat with remaining patties.
Assemble burgers with buns, fry sauce, pickles, onions, etc. and enjoy!
