Cut the eggplants across into 1/2-inch thick slices. Place them in a colander, sprinkle with salt and leave to drain for about 30 minutes. Rinse the eggplants and pat dry with paper towels. 

Brush them with a little olive oil, place under a preheated grill and cook for 5-6 minutes on each side until charred and tender.

Meanwhile, whisk the rest of the oil, the vinegar, mint, garlic and a little salt. Dress the eggplants with this mixture while they are still hot. Set aside to cool. Serve with roasted preserved peppers and zucchini as a first course.

Serves 4.
