I just had a weird meal.

Sous Vide chicken, with roasted vegetables, mange tout, and spinach. It was the only meat choice of three (the other options being inedible). It was also served cold. 'Chilled'. Cold chicken isn't uncommon, but cooked spinach, and mange tout, chilled, and then served? But the stewardess showed me the menu, and, to my incredulity, that is how it was described. The stewardess was lovely, and was happy to put it in the oven, which made it edible.

Cold oatmeal is, apparently, not unique.
