Insalata di Tonno e Patate

The Tuscan salad of tuna and beans is not so much famous as infamous but when there are fresh white cannelloni beans available it is still a delicious summer dish. An alternative, suggested by a fishmonger in Pisa’s market, is to substitute tiny new potatoes for the beans. He uses fresh tuna, barbecued over a chestnut fire, but the dish is still tasty when made with good tinned tuna.
