Preheat a skillet over medium heat. Preheat the oven broiler on low.
Mix together the ground beef, steak seasoning, and Worcestershire sauce. Season generously with salt, and form into even patties.
Once the skillet is hot, cook burgers on both sides getting a nice crusty char to desired doneness (see below) using a thermometer. When the burger is 3/4 of the way cooked to your liking, add the cheese and place under the oven broiler to melt.
Lightly toast the buns. Spread the ketchup on both halves of the bun or serve on the side. Place the lettuce on the bun followed by the burger and tomato. Serve with pickle or your choice of condiments.
