Cooking Directions

Step 1

Position rack in upper third of oven; preheat broiler. Line a broiler pan with foil.

Step 2

Gently mix beef, mushrooms, breadcrumbs, Worcestershire, thyme, salt and pepper in a medium bowl until combined. Shape into 4 patties and place on the prepared pan. Broil until cooked though, 4 to 6 minutes per side.

Step 3

Meanwhile, toast bread. Rub each slice of toast with garlic.

Step 4

Place 1 patty on each piece of toast, top each with 2 teaspoons relish and cover with a slice of cheese. Remove foil and place the sandwiches on the pan; broil until the cheese is just melted, 30 to 60 seconds.
