In a deep-frying pan, put an amount of oil so that it is about 2 inches high.
Get 3 wide, high-rimmed plates. In the first dish put the flour. In the second dish, put the eggs, salt and pepper. Using a fork, stir the eggs to mix. In the third dish, put the breadcrumbs.
Put a slice of eggplant in the flour. Turn it on both sides to cover with a thin layer of flour. Put the slice in the eggs and flip it until it is covered in a thin layer, then put it in the breadcrumbs. Flip the eggplant slice into the breadcrumbs, pressing it lightly to cover with a generous layer of breadcrumbs.
