Preheat oven to 350F
Spray a 12 count regular-size muffin cup with non-stick spray.
Press half of a bun, cut side up, into each muffin cup, pressing to thin out the bun some.
In a large skillet brown and crumble your ground beef and drain.
Remove from heat.
To the meat add your worcheshire sauce, onion and salt and pepper to taste.
Place a quarter of each slice of cheese into each cup.
Divide 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.
Sprinkle each one with sesame seeds, a drizzle of the thousand island and a pickle chip.
ENJOY!
