I just chop iceberg lettuce to make a "bed". Add a large mound of crab, surround it with quartered hard boiled eggs and avocado slices. The Louie dressing I use is a combination of mayo, catsup and chili sauce. I mix and taste until I get it right, then drizzle it over the salad and finish with a good squirt of fresh lemon juice.
BTW, if you can't get fresh crab, the lump crab in a can at Costo (Philips) is very good.
