Peel 2 small eggplants and cut into 1/4-inch-thick rounds. Put 1 cup flour in a shallow bowl, beat 4 eggs in another bowl and put 1 cup breadcrumbs in another. Coat the eggplant in flour, then egg (let any excess drip off), then breadcrumbs. Heat 1/4 inch of vegetable oil in a large skillet over medium-high heat. Fry the eggplant in batches until golden brown, 2 to 3 minutes per side (add more oil if necessary). Drain on a rack and sprinkle with salt.
