Put the flour in a shallow dish. Whisk the eggs and 1/2 teaspoon salt in another dish. Put the breadcrumbs in a third dish. One at a time, hold the peppers by the stems and dredge in flour, then dip in the beaten eggs, letting the excess drip off, and roll in the breadcrumbs; dip in the eggs again and reroll in breadcrumbs. Transfer to a plate and refrigerate until the coating sets, about 20 minutes.
