Need an appetizer to bring to a crab boil

Something that will go well with boiled crabs. Thinking cheese stuffed jalapeños wrapped in prosciutto topped with a fig or maybe cut up grilled smoked Boudin. I am even considering cured salmon which I have never done before.

It needs to be finger food. Maybe barbecued shrimp already peeled with the tail section still on (like a shrimp cocktail or shrimp remoulade). I was even thinking of some kind of crawfish salad plated out on endive spears.

Any other ideas would be appreciated
