In a medium sized bowl, mix the ground beef, red onion, Frank's hot sauce, blue cheese and Montreal Steak Seasoning together until well mixed. Form into 8-10 patties (the size of your buns you are serving the burgers on) and grill on a hot grill on both sides until the center is no longer pink and the meat is cooked through. Spread a generous portion of blue cheese (or ranch dressing) on both sides of the bun. Place the patty on the bottom bun and top with sliced avocado, red onions, tomatoes and lettuce. Drizzle extra Frank's sauce on top of the burger and serve.

HEALTHIER OPTION: Serve the hamburger on a bed of lettuce instead of on a bun. Or, serve on a whole wheat bun. Serve with lowfat blue cheese dressing.
