Sicilian Eggplant Rolls

Eggplant is the Sicilian vegetable par excellence, often appearing several times in a single meal in different guises. Here fine-textured white eggplant slices are rolled around prosciutto and mozzarella, then sauced with a light sweet-sour purée of tomato. If no white eggplant is available, make this with the dark, as they do in the dish’s land of origin.
