This variation on parmigiana di melanzane hails from Puglia. The recipe for this Puglia-style casserole sometimes calls for using zucchini instead of eggplant, along with olive oil, flour, eggs, tomatoes, mozzarella, cooked sausage meat, and grated Parmigiano-Reggiano.
The eggplants or zucchinis are peeled, sliced, dredged in flour and eggs, then fried. Tomato sauce is ladled into a baking dish, followed by fried eggplant slices, mozzarella, and sausage meat. The layers are repeated, ending with tomato sauce and grated Parmigiano-Reggiano.
