Cut hard-boiled eggs in halves. Take out the yolks, leaving two cup-shaped pieces. Mix the yolks with an equal quantity of softened bread; season with salt, pepper, and parsley. Add a little raw egg to bind the mixture, and fill the spaces from which the yolks were taken. Round it on top to give the appearance of a whole yolk. Cut a little slice off the bottom of the egg, so it will stand firm. Place them in the oven just long enough to heat, and serve standing, on a dish covered with white sauce.
