I have one for cow liver, and another for veal....

Cow liver schnitzel
Cut the liver in scallops and marinate during 4h with white wine, sliced garlic, bay leaves, salt and pepper. Drain, and pass the scallops through milk, and then through flour, mixed egg and finally crumbed bread.
Mix butter with olive oil and fry

Italian veal liver
Poor cognac over the sliced liver and season with sal and pepper. Let aside. After 2h, flour them and fry with a mix of butter and olive oil
Put them in a dish that can go to the table and the stove and poor over lemon juice. Put on top of each slice 1 dry ham slice and 1 cheese slice. Put them in the the stove to gratin, and serve covered with a very well seasoned tomato sauce.

Hope this helps....
