This one is called something that technically translates to "treacherous stab in the back from a trusted companion" and is colloquially shortened in Basic/English to "stab rolls." It involves organ meat (preferably heart and liver, for being stabbed in), bitter greens, and cacao powder, all wrapped up in a large honeyed egg noodle and pinned savagely together with a toothpick.

It is something of an acquired taste. Those who acquire it tend to do so, appropriately, with a vengeance.

(I get along very poorly with bitter foods, so I am not actually likely to try fixing this.)
