In the third dish combine the bread crumbs, cornmeal, 2 tablespoons Parmesan and season with salt and pepper, to taste. Slice the eggplant into 3/4-inch slices. Dredge them in flour, then in the egg wash and then in the bread crumbs. Arrange the eggplant on 2 sheet trays fitted with a racks and bake in oven until crispy, about 20 to 25 minutes.
