In a bowl place the meat and add in the worcestershire sauce, BBQ sauce, ketchup, hot sauce, egg, breadcrumbs, salt, pepper, garlic powder and parsley. Combine until all the ingredients are mixed well into the meat. Divide the meat into 6 parts and form your burgers. Using your fingers create a well in the centre of the burger so the middle is thinner than the edges for more even cooking.
Cook the burgers about 4 to 5 minutes per side. When you flip them place the blue cheese on top and let it melt while the burger cooks through.
Thinly slice the cabbage. In a bowl mix together the cabbage, vinegar, salt and pepper.
Build your burger by layering the bun, lettuce, meat, tomato, onion, and cabbage slaw. Serve with a side of celery and carrot sticks just like a basket of wings would be served.
