Really, about the only thing I don't like is most white fish. I cannot stand catfish. I'm trying to learn to like fish, because it sounds so good. You always hear pro-chefs describe how delicate and flaky, and fresh tasting fish is, but 99% of the time I've been near fish it smells nasty, and tastes just like it smells. They also say this is a sign of less-than-fresh fish, but honestly the only time I've been around fish that doesn't smell that way is fresh caught or the fish markets at Pike Place, which is such a pain in the ass to get around that I just can't bring myself to go there.
Strangely, the same does not apply to sushi (except that I usually can't stand the texture of raw fish), good tuna, and occasionally salmon and mahi-mahi.
Also, the texture of real bananas kills me. I can handle them in pie form, or pudding form, or bread form, and I love the flavor of bananas so popsicle form kicks much ass, I just can't peel a banana and eat it.
Oh, and the aforementioned evil that is Hershey's chocolate. I am exceptionally pissed that they bought out Scharffen Berger's chocolate and then shut down the plant in Cali, that was some of the best baking chocolate I've ever used (flourless chocolate cake, FTW!).
Aside from that, the only thing I can imagine really hating on the previous list is that boxed mac-and-cheese with tuna. Or any mac and cheese with tuna, really. Tuna casserole is one thing, mac-and-cheese with tuna is an abomination.
Oh, and Krisken's breakfast sandwich sounds amazing.
