I moved to JA permanently many years ago when I was in my early 20's -- I didn't know how to cook at all, I didn't even know how to cook rice. It can be easy to spend a lot of money on food (if you don't know how to cook), or shop. Finally we got it down to a menu, we were all VERY young, very inexperienced cooks. Eggs, scrambled, omelette, whatever -- they are pretty cheap too, bread, mango jelly on the bread, potatoes, again pretty cheap.
Another lunch time / dinner time thing that we would cook was "stuffed cabbage" -- rolling the cabbage with rice, almonds (lots of injuries to the fingers) deep west end has lots of almond trees, but you have to crack each and every one.
The "chicken" ... many chicken, feeling sorry for, gotta get used to getting rid of those feathers... YUK. Stuffing then with almonds, scallions, onions and so on.
Re: "the 'Pork thing'" - the great majority of the Jamaican population really and truly disses the people who 'deals with pork' -- they are of the belief that it is a DEVIL thing -- "PORK" equals corrupted people, people "unclean" ...
