ダンジョン飯 (Dungeon Meshi) is one of these cute little gimmick manga that are just a joy to read, but whose ideas might be a bit too far out for everyone involved
Our heroes are a group of typical D&D-style adventurers who make a living descending into a giant dungeon that someone found a while back. This dungeon is so big that it contains whole cities and forests, all underground, and it attracted a veritable support infrastructure for all adventuring purposes just outside of it (including a resurrection service).
While our protagonists are already pretty experienced and far along they run into a red dragon who promptly eats Farin, one of their spellcasters, just after she managed to teleport the rest of the group to safety.
The group (headed by Farin’s brother Laios) decides to head downwards again, to rescue and revive Farin before she is digested by the dragon. In this venture they hit one of the typical snags of adventure life: they have neither food nor resources after the failed run in with the dragon, and they don’t have time to gather more if they want to be in time. So Laios concocts a rather harebrained scheme: they will eat their way downwards. There are monsters in the dungeon after all, and a lot of them are edible. Or at least they should be.
Soon enough they are joined by Senshi, a dwarfish warrior chef with great knowledge of the dungeon and its inhabitants, and they start making headway through all the delicacies of the dungeon.
On their way down to the dragon the heroes meet multiple typical dungeon monsters, and somehow they find their ways to make them into rather delicious looking meals. The manga even provides us with recipes for these dishes, although it might be kind of hard to find basilisk or living armor in our world.
But here’s an interesting idea that I would love to see in a game: cooking the monster.
I don’t think this ever got done properly, but I bet someone somewhere created some classes for dungeon cooks. What if the player characters would venture down into the dungeon specifically to find some rare delicacy that otherwise could not be found anywhere else? Or what if we focus a roleplaying game not only on the survival aspect of it all, but also on how exactly one would make those things they kill or purchase in the dungeon edible. This of course would demand not only that the DM would know what the hell he/she is talking about, but also that the players know how to cook to be able to make sense of the scenario.
