Get out and measure your ingredients.
Preheat oven to 350 degrees.
Spray a 12 count regular-size muffin cup with cooking spray.
In a large skillet brown and crumble your ground beef and drain. Remove from heat. To the meat add your worcestershire sauce, onion and salt and pepper to taste.
Press half of a bun, cut side up, into each muffin cup, pressing to thin out the bun some.
Place a quarter of each slice of cheese into each cup.
Divide meat mixture evenly among muffin cups.
Bake 10-12 minutes until the buns are lightly toasted.
Remove from the oven and immediately top each cup with another quarter of the cheese slices.
After 5 minutes remove from pan and place on platter or cutting board.
Sprinkle each one with sesame seeds, a drizzle of the thousand island.
And a pickle chip.
Serve and enjoy every bite!
