Starting with turkey, layer in order as written, in a fairly deep pan (loaf pan works well), ending with potatoes. Wrap well with aluminum foil and freeze until needed. Bake with foil left on covering, and a baking sheet underneath, at 350* for about 1.5 hours. You can take out in the morning, and then it won't take as long to heat up. Take foil off top for about the last 15 mins.
