It'll sound stupid but I'd have to say one of the 2 ways I make oatmeal, and also certain cerials. It's about the only think I can eat, I'm just glad I find them tastey, imagine if I disliked the tastes.
Back when I could eat normal food I use to like cheese a lot, Pizza with various tippings, including sometimes pineapple, chilly with no beans. To name a few foods I liked a lot back then.
