Divide the ground beef into 4 equal portions and roll them into balls. Do not overwork the meat.

Preheat a griddle or skillet over medium-high heat. Place the beef balls on the hot surface.

Using a spatula, smash each ball down to form a thin patty. Cook for about 2-3 minutes until a crust forms.

Flip the patties, add a slice of cheese to each, and cook for an additional 1-2 minutes until the cheese melts.

Toast the burger buns on the griddle for 1 minute.

Place the cooked patties on the bottom half of each bun. Top with lettuce, tomato, pickles, ketchup, and mustard.

Cover with the top half of the bun and serve immediately.
