Grease a baking dish and preheat the oven to 375.

On a clean work surface, press each biscuit into a 3 to 4 inch circle with your fingertips. Spoon a bit of the chopped onion into the center of each disk. Arrange a slice of cheese over each.

Mix the beef with the Worcestershire sauce, burger seasonings and a dash of salt and pepper in a bowl. Form the beef mixture into 10 small disks, about 1 ½ “ wide and a ½” thick. Place the small patties over the cheese and carefully cup each disk in your hand and work the edges over the patty, pinching shut to seal.

Place, seam side down in the prepared baking dish. Nestle each of the biscuits in the dish with about a 1” on either side.

Brush the tops with melted butter.

Bake 15 to 17 minutes, until golden brown. Remove from oven and allow to cool 3 to 5 minutes before serving with pickles and mustard and ketchup for dipping.
