Preheat gas or charcoal grill to 400°F. Shape Ground Beef into eight ¾-inch thick patties. Season with salt and pepper. Make a small indention in the center of the burger with your thumb.
Place burgers on oiled grates and grill for approximately 5 minutes on one side. Flip once, grilling on the other side for 5 minutes or until internal temperature reaches 160°F with a meat thermometer inserted into the thickest part of the burger.
Prepare dressing by whisking together ranch dressing and buffalo wing sauce in a small bowl. Set aside.
Place burgers in buns and top with dressing, blue cheese crumbles, lettuce and tomato.
