Literally translated, this Italian term means "jump mouth." It refers to a Roman specialty made of finely sliced veal sprinkled with sage and topped with a thin slice of prosciutto. It's sautéed in butter, then braised in white wine. Sometimes the meat layers are rolled and secured with picks before being cooked.
