Does anybody in your crowd like seafood? Seems like you have a good amount of vegetarian dishes, so I would probably throw in something like a shrimp cocktail or clams casino, and/or another meat option like buffalo chicken dip, or beef satay.
I live in Europe and have not had good luck with the seafood in my country. I would look up clams casino if it calls for canned clams. Buffalo chicken dip is a good idea too!
