Thinly slice the celery, dice the onion and finely chop the parsley. This can all be done quickly and easily in a food processor.
Put the bread cubes in a large mixing bowl. Stir in the celery, onion and parsley. Stir in the beaten eggs.
Heat the milk and butter until the butter is melted but do not boil it. Stir until mixed.
Pour the liquid over the bread mixture and mix well. Sprinkle with salt and pepper.
Place the stuffing mixture in a large baking dish, cover it and bake at 350 degrees about one hour or until the stuffing is golden brown on top. Check the stuffing several times while baking and add a little water to keep it moist if needed.
