In a large pan, brown ground beef, bacon and onion until cooked. Drain any grease.
Add cream cheese, ketchup, barbecue sauce, mustard and Worcestershire sauce. Stir over low heat until cream cheese is melted. Allow to cool.
Roll each biscuit out very thin. Place 2 tablespoons beef mixture on each biscuit and add 1 square of cheese. Wrap the biscuit around the beef/cheese and tightly seal the edges.
Place biscuits on a parchment lined pan seam side down. Brush with egg white and sprinkle with sesame seeds.
Put them in the oven and turn down the heat to 350 degrees. Bake 13-16 minutes or until lightly browned.
