The tuna sandwiches can be kept at room temperature for up to 3 hours.
Even a meal that arrives between two slices of bread deserves to be matched with the right wine. This Italian tuna sandwich merits an equally flavorful Mediterranean bottle. Look for a dry rosé from Sicily with gutsy fruitniness to offset the saltiness of the tuna. Alternatively, look for a Sardinian red with dried-spice character and peppery fruit flavors which meld with the olive, thyme and pepper of the sandwich, while its acidity and firm tannins are a clean counterbalance to the tuna and blackolive dressing.
