There was this great little place in Metarie that made the best "barbecued" shrimp/crawfish (depending on the season). It didn't taste like anything I've had before or since, and you literally wanted to lick the plate. Bknox, mufalettas are SO easy to make at home, you needn't deprive yourself.
Buy a good, firm, round loaf of bread (a boule in some stores). Slice in half horizontally, then scoop out a little of the bread from each side to form a sort of cavity. Brush with olive oil.
Make a sort of tapenade (only coarser) from both green and black olives, diced onion, roasted red bell peppers, lots of garlic and olive oil. A sprinkle of good red wine vinegar. At the last minute, toss in the bread crumbs you've removed from the loaf. Fill the hollow in the lower slice of bread with half of the olive salad. Then pile on slices of salami, ham, roast beef, etc and some provolone, swiss, cheddar cheese. The varieties of meats and cheeses is up to you. Pile on the rest of the olive salad so it fills in the hollow in the top piece of bread. It is fine right now, but I also like to toss it into a hot oven for just long enough to crisp the surface of the bread. slice into wedges.
Messy, but fun. A great party food. My favorite is at Napoleons in NO.
