Preheat the grill to 450 -500 degrees F.
Brush the patties with Worcestershire sauce and season with sea salt and black pepper. Keep the patties in the refrigerator until you start grilling.
Heat the pulled pork in a small pan. Add a little water to the pan so the pork doesn't dry out. You can also add some barbecue sauce to the pork, or additional seasonings. Keep warm until needed.
Place the patties on the preheated prepared grill season side down. Cook for 4 minutes and turn the patty over to continue cooking.
Depending upon how well done you want your burger you may turn the meat twice more. This will help the patty cook evenly.
When the burger is almost done, place your hamburger buns on the grill to toast them.
When the burger is at the desired doneness (use a meat thermometer to check the internal temperature) place a slice of cheese on top of the burger. Allow the cheese to fully melt.
Remove the burgers from the grill and place on a plate. Allow the burger to rest for a minute before placing it on the bun. You will get some juices flowing out of the meat. This could make the bun soggy. If you don't mind a soggy roll and want the added flavor of the juices, you can place the burger directly from the grill onto the bun.
Top the cheeseburger with preheated pulled pork, barbecue sauce and bleu cheese crumbles. Add the top of the roll and serve.
