I culled this recipe from a Mardi Gras website. The olive salad gives this sandwich its authentic taste. I made this as part of a Mardi Gras lunch at work and even folks who do not like olives enjoyed it. The mixture of pickled cauliflower, carrots, celery, and pepperoncini is called gardeniera and can be found in the relish/pickle section of your grocery. Also, I omitted the salt. Cooking time for this one is really refrigeration time for the compiled sandwich. I let the olive salad flavors meld for 1 week. It was worth it!
