doing a BBQ chicken leg for the rice. The rice they serve here is 'rice 'n peas' either black eyed peas, the big green lentils or more usually beans (red ones).
Pork is also popular and you could do a stew with it, like "stew pig" which is essentially a gravy dish. Use lots of onions and a little seasoning pepper...(this looks like the habenero but not quite as hot)....green peppers, celery and small bits of corn on the cob, carrots and pumpkin.
All local places have a bottle of hot sauce on the tables...mostly "Matouks" but if you can't find that and it is sinfully ...roof-of-the-mouth-burning-off-in-big-flakes-hot, have a tobasco bottle instead.
Fungi is also popular, essentially soft grits-like polenta.

And then 'Accras' are very popular on the French islands....salt cod cakes served with a 'sauce chien'.
I am sure the meal will be very well recieved.
