"Tonno" is Italian for tuna, and the name of this dish refers to the primary ingredient in the sauce. The tuna is blended with capers, olive oil, and lemon juice to make a rich, flavorful sauce that is traditionally served with veal cutlets. The sauce can also be served chilled over room-temperature chicken.
