Cut the liver into hand-sized pieces and cut them into thin layers. 

Draw squares on one side of the liver layers with the tip of the knife. 

Cook the tomatoes and peppers over a coal fire.

Then, cook both sides of the livers at 10 cm. above the fire. 

Serve as you wish with tomatoes and peppers.

Note: Generally, it is the grilled form of the fresh liver. It should be cut very thin and the top should be marked in square-shape.
