Cut the eggplant in half, make a few incisions in the white part and boil them for about 10 mins. Drain them and let them cool off.
Preheat the oven at 400F.
In a bowl, add the Diced Tomatoes, the olives cut in half, the anchovies cut in small pieces, the pepper, the oregano, the garlic, some peperoncino, as desired, and the basil. Mix well, EV olive oil and salt and mix well again.
Take a baking pan, coat it with olive oil and position the eggplant halves facing up. Fill each eggplant with the mix. Drizzle some more olive oil and bake for 30 mins.
