PNG food is mostly starches, with a little protein thrown in. Cooking banana, pit-pit, lots of greens.. Aibika is a favourite, along with pumpkin tips and "charko lip".. Choko vine tips!. Foods here are often "grissed", boiled in coconut cream.
I love food cooked "aigil", like a mumu, on hot stones covered in earth, or mambu, stuffed ito bamboo tubes and cooked over a fire.
We get lots of fresh seafood here on the coast, too!
As for "western food", there's not too much we miss out on, with the local supermarkets having a great choice of Western stuff. I can even get great Mexican ingredients up here!
