1. Place a portion of the lettuce on each of four plates. Drizzle with some of the dressing, and then top with one of the burgers. Sprinkle with the tomatoes, onions, crumbled blue cheese, crumbled bacon, and optional avocado. Serve with additional dressing, as desired.
You may cut the lettuce into more traditional wedges, but the thick slices create a flat surface on which to place the burger and make the salad easier to eat. As an option to the iceberg lettuce, two hearts of romaine may be used. Slice them lengthwise.
