Lungs as food

Lungs of game or livestock are a variety of offal used in cooking and butchery.
Lungs are rarely used in English-speaking culinary traditions, with the exception of the Scottish national dish haggis.
In Malaysia, slices of beef lung are coated in flour and turmeric powder, deep-fried, and sold in packets at street markets. These are a very popular snack eaten with chilli sauce and a dash of vinegar.
Bopis is a piquant Philippine dish of pork or beef lungs and heart sautéed in tomatoes, chilies and onions.
