The TVTropes Trope Finder is where you can come to ask questions like "Do we have this one?" and "What's the trope about...?" Trying to rediscover a long lost show or other medium but need a little help? Head to Media Finder and try your luck there. Want to propose a new trope? You should be over at You Know, That Thing Where.
I don't know that we have a trope for cooking roadkill specifically, but it would fall under Lethal Chef. And possibly Mystery Meat if they serve it to someone without telling them what it is.
Edited by BattleMasterLethal Chef only applies if the food is actually life-threateningly bad, I don't know if there's actually a trope about eating animals or not.
~forum signatureI'd file it more under Cordon Bleugh Chef or Foreign Queasine than Lethal Chef- there's no technical reason you can't cook and eat fresh, mostly intact roadkill. In some areas it's actually a semi-common practice protected by law.
See also Reduced to Ratburgers for when someone's eating roadkill out of desperation rather than pragmatism or personal choice.

Do we have a trope where someone finds roadkill and either eats it raw or cooks it as a meal? Can include intentionally killing an animal to do that?
