Spicy Blue Cheese Hamburgers

In a medium bowl, mix together the ground beef, blue cheese and onion. Season with Worcestershire sauce, mustard, and pepper. Mix well, using your hands if necessary. Form into four patties, and place on a plate. Cover and refrigerate for 1 hour.

Preheat an outdoor grill for high heat. Remove the hamburger patties from the refrigerator, and pour enough hot wing sauce over them to cover the top surface. Allow to sit for 10 minutes.

Place hamburgers on the hot grill, and cook for about 5 minutes per side, until no longer pink. The internal temperature should be at 180 degrees F (85 degrees C) if taken with a meat thermometer. For extra spicy burgers, baste with additional wing sauce while cooking. Serve on buns.
