Lemme see if I can find last year's menu, then. Admittedly, Aunts will be bringing a couple of dishes, so there's the answer to what we're not making.... *chuckles*

Twenty-plus pound turkey.
Gravy.
Dressing. We bake it separately, so it's dressing, not stuffing, which would be cooked inside the bird. But that's a distinction that's slowly getting lost.
Biscuits/yeast rolls, at least one and generally both.
Green beans (and/or green bean casserole) -- cooked with either bacon fat or ham pieces and an onion. Say... four quarts, probably?
Corn (probably 2 quarts and a pint).
Mashed potatoes (fifteen pounds or so).
Cranberry salad.
Five-cup salad.
Waldorf salad. (Aunt 1)
Green salad. (Aunt 2)
Vegetable tray.
Pimento-cheese celery.
Cream-cheese celery.
Pumpkin pie.
Pecan pie.
Cheesecake.
Brownies.

Gyah. I'm still missing something, I know it.
