Tips: For the preserved Tuna, we confit our own from trimmings that are left from our tuna crudo entrée. But tinned tuna in olive oil will work as well. (Please use the best brand you can afford. It definitely makes a difference to this recipe and the environment.) keep the oil for the Piadina. Also, if you confit your own tuna, using that pure olive oil makes a great mayonnaise and also means your giving a second life to the oil.
