Okay. If you've been following my recipe blog, you know that anything that I cook with pineapple I call "Hawaiian-Style." For me, pineapple is very representative of the islands, in addition to macadamia nuts or macaroni salad (smile) -- at least when talking cuisine. In the Philippines, there is a popular way of cooking called "escabeche," which basically is a dish -- usually fish -- cooked in sweet and sour sauce. Escabecheng Tilapia (whole fish) is quite common.
This recipe has all the elements of escabeche plus ambiance of Hawaii, represented in the pineapple ingredient. Rather than using whole Tilapia, I use fillets which may be easier to obtain, frozen, from your favorite supermarket.
