After 24 hours, turn bread over so both sides can stale.
Leave out on kitchen counter until ready to use in recipe.
Remove turkey neck and giblets from turkey and place in a large stock pot.
Fill with water and sprinkle heavily with salt and pepper; sprinkle with dried parsley.
Bring to a boil.
Reduce heat and simmer for about one to two hours.
As water evaporates, continue adding more as needed every 20-30 minutes.
(The turkey broth can be rendered the day before you need it in the recipe if you need to make it in advance.)
In a large skillet or Dutch oven fry sausage until no pink is remaining.
Use a hamburger chopper to break the meat down into very small pieces.
(The sausage can be cooked a day in advance if necessary to cut down time needed to prepare recipe).
Add diced onions, celery, onions, parsley, sage, salt, and pepper.
Cook until veggies are tender. Set aside.
Set bread out on cutting board.
Cut bread slices in cubes and place in a large mixing bowl.
Add sausage and apple mixture.
Scoop broth out of the stock pot and pour over the bread and sausage mixture.
Add enough to moisten all the bread, but not make the mixture soupy!

Place remaining stuffing into a greased 3-qt. casserole dish.
Bake at 350 degrees about 45 minutes to 1 hour, or until done.
