La coratella is a traditional dish from Rome. 
It is a stew prepared in a large pan - una padella. 

The stew is made from a lamb's heart, lungs, liver, spleen, kidneys, windpipe and pancreas.  The sliced pieces are sautéed in the pan with ingredients such as olive oil, wine, herbs, onion and artichokes.

Originally, it was a dish for poor people who could not afford the best cuts of the meat.
