Toast Di Tonno

Toast Di Tonno is a simple open-faced sandwich or toast topped with a tuna mixture, commonly found in Italian and Portuguese coastal cuisines. The dish likely evolved from the Italian tradition of using preserved tuna, olive oil, and capers on crusty bread, while in Portugal, canned tuna is a pantry staple. Key ingredients typically include high-quality canned or fresh tuna, extra-virgin olive oil, lemon juice, capers, and often anchovies or olives, served on toasted sourdough or country bread. A great version is distinguished by the tuna’s richness—preferably packed in oil, not brine—and a balanced acidity from lemon, with the bread remaining crisp beneath a generous, moist topping. Fresh herbs like parsley or chives add brightness.

Regional variations abound: in Italy, additions such as sun-dried tomatoes, arugula, or mozzarella are common; in Portugal, local ingredients like Queijo de Azeitão or piri-piri peppers may be incorporated. At O Portinho in Portinho da Arrábida, Portugal, a notable version is served, as highlighted by the creator *Sentieri Golosi*. There, the toast is prepared with premium Portuguese tuna, a drizzle of local olive oil, and a sprinkle of sea salt, emphasizing the freshness of the seafood and the simplicity of the coastline. The dish exemplifies how a humble combination can become a regional specialty when executed with care.
