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.
The recipe is courtesy of the Italian Academy of Cuisine. The thing that sets the Pugliese parmigiana apart is that the eggplant slices are coated in eggs and flour and then fried. Besides eggplant, the Pugliese parmigiana has tomato sauce, mozzarella, and Parmigiano-Reggiano as the main ingredients, as stated in this recipe.
