Meat Stuffing

1 pound ground beef
1 pound ground pork
1 pound ground turkey
1 onion, chopped fine
1 cup bread crumbs
3 ribs celery, chopped fine
1 (8 ounce) can water chestnuts, drained and chopped fine
1/2 cup chopped parsley
2 teaspoons salt
2 teaspoons pepper
2 teaspoons poultry seasoning

Combine all ingredients well, but try to keep the mixture loose. Stuff turkey cavities loosely. Roast turkey at 325 degrees F, but add about 1/2 hour more for the stuffing to cook.
