Step 1

Preheat a grill for high heat. In a medium bowl, lightly mix together the ground beef, Worcestershire sauce, liquid smoke, and garlic powder.

Step 2

Form into 3 patties handling the meat minimally. Over handling will make the meat tough.

Step 3

Brush both sides of each patty with some oil. Season with salt and pepper.

Step 4

Place the patties on the grill grate and cook for about 5-8 minutes per side or until cooked to your liking. I sometimes cook these in an iron skillet also.

Step 5

Saute sliced onion in butter in skillet until soft and done.

Step 6

To make grilled cheese put buttered bread 2 at a time in large skillet. Brown both sides and add 2 slices cheese to each sandwich.

Step 7

Put grilled hamburger and sauteed onions inside one grilled cheese sandwich.

Step 8

Top with a second grilled cheese.
