After washing the eggplants, cut them lengthwise into 1/4 inch slices , arrange them in a colander in your sink or on a platter, and cover them with kosher salt on both sides.

Allow them to rest and 'weep" the bitter juice out for one hour.

Keeping the eggplants in the colander, rinse them well under cold running water to eliminate all traces of bitterness and salt.

Blot dry with paper towels.

Arrange the eggplants on a wide tray and cover them with a mix of oil, vinegar and salt, and freshly chopped mint leaves.

Allow to marinate for 30 minutes.

In the meantime, combine the tuna (drained), olives, capers (drained and rinsed), and anchovies (rinsed) in a food processor until they form a smooth, creamy paste.

Grill the eggplants on a heavyweight grill pan, turning them and brushing them with the marinade, until cooked through.

Allow to cool for a few minutes, then spread the tuna mixture on one side of each eggplant slice, roll up and secure with a toothpick.

Serve warm or at room temperature.

Note: Eggplant in Italy was apparently abhorred by non-Jews until the end of the 1800s. Its Italian name, Melanzana, is said to derive from the Latin "Mela Insana" (Bad Apple) because it was believed to be poisonous and cause fevers that would make people lose their minds. But in the 20th century the purple fruit took the country by storm, and is now the star ingredient in some of the most popular and world-famous Italian dishes.
