My personal favorite is stuffing.
My mom makes a rice & sausage stuffing that is just second to none!
That, the gravy, the mushroom pie, candied and baked yams/sweet potatoes, a veg... truthfully I could do without the turkey.
She tried something new this year. My dad was talking to a friend who told him that he got his frozen turkey quartered by the butcher as the whole thing would be too much. My mom tried it, getting it cut in half instead, as there were only 4 of us and it was a 17 lb bird. Problem is, you can't really stuff it that way, but it is a practical solution if the bird is too big -- the other half is in the freezer.
I'll be going over there later for turkey soup.
