Another idea: if it's a relatively sour pineapple that's out of season, blend it into juice and use it to brine/marinate chicken. Pretty much any kind of marinade will work with pineapple, I like to mix into the pineapple juice whatever I have on hand, ginger, garlic, soy sauce, sake/mirin, etc. If I have citrus, whether lemon, lime, orange, mandarins, etc, it always comes out super tasty 
If you need a starting place, google "El Pollo Loco copycat chicken marinade".
Little bit of a waste possibly, since pineapple juice is way cheaper from the can versus fresh, but sometimes the grocery store pineapples are picked way too early for transport.
