Lightb, the only time you have to eat for the Mitzvah is when you have to eat for the Mitzvah. And in that case you have to eat a specific amount, not just taste a little. As in Hamotzi at the Shabbos seuda. As in Matzah and Maror on Pesach (no wrinkling your nose and saying it doesn’t appeal), and arba kosos if we’re including drinking as well as eating. As in any food at all on Erev Y”K.
There are other foods that are a good idea, like the fruit you no doubt just ate on 15 Shvat, and the fried foods you may have indulged in on Chanukah, but there’s no need to make yourself sick.
I do miss the gefilte fish threads though.
Sushi inspired threads just aren’t the same…
