Generally nothing, because, even though there are always dishes I wouldn't touch with a 10 foot pole, there is always enough food I do like for me.
The one pick I can agree with though is Ham.
Close, but not quite. Ham is acceptable any time EXCEPT THANKS-FUCKING-GIVING. THANKSGIVING IS TURKEY. END OF GODDAMN STORY. Although, again, if both turkey and ham are served, that's fine. But if its like, "We're not having turkey this year, we're doing ham instead," Fuck you.
That's it, I'm banning YOU from Thanksgiving. 😜
