Next, chop onions, celery hearts, (Mushrooms are optional), and sauté in oil in a large skillet adding chicken meat, garlic, pepper, and salt. Beat the eggs thoroughly, and pour over bread cubes. Then pour the sautéed mixture over the bread and eggs. Use the saved water from boiling the chicken meat to add moisture to this mixture, do not let it get too soggy though. Fold together gently. Stuff turkey neck and body with this stuffing, allowing for expansion. Cook extra stuffing in a covered pan at 350 degrees for about 1/2 hour.
