Well, there's one particularly "eww" food that a lot of Filipinos eat (that I don't), which is called "balut." Just do a google search for it.
For a more mild Filipino favourite, you could check out something called "lechon." It may not be all that strange to some Westerners, but it may sure freak out all of your vegan buddies. =P Basically, you just roast a while pig! If you can find a Filipino catering service to help you out with a party, some of them will roast the whole pig (or several of them if you have the cash and the need) right there in your yard!
Any ideas, Katoliko?
