Hope it all goes well for you....
My advice - even though it's near summer she'll still need some warmish clothes (long sleaved tops. trousers/jeans etc) - I've just returned after over 2yrs in Philippines and it's still bloody cold - at first I was sleeping fully clothed - now in this sunny weather I still get goose bumps lol
For foods - depending on her current lifestyle/location - if she's from close by the waters (so to speak) then I assume she'll eat anything that comes out of the ocean from crabs to all kinds of fish - the fresh type (our available fish here are restricted but tapia is a good choice for starters - she'll know that one.) and of course rice - plain boiled bugas - no added anything - just pan after pan of plain boiled rice for breakfast, dinner and tea....
Our pork is leaner where as baboy is straight from the pig with everything attached.
Plain grilled chicken from the superstores will almost be like her lechon manok except you'll need to find the soy sauce or whatever it is they use.
