Directions

1. Preheat grill to high. Shape the beef into eight 4-oz. burgers and season both sides with salt and pepper to taste. Grill for 3 to 4 minutes on each side for medium-rare, or to desired doneness. During last minute of cooking, add 2 slices of cheese (one of each kind) to each burger; cover grill and let the cheese melt, approximately 1 minute.
2. Meanwhile, brush olive oil on both sides of the onion slices and season with salt and pepper. Grill onions for 3 to 4 minutes on each side, until golden brown.
3. Place burgers on buns; top with horseradish mustard, lettuce, grilled onions, pickles, and ketchup, if you like.
