I've just looked at a number of sites that plan most all of the sides to be cooked the day before and heat them up before the meal. Looks like a good idea to me. I even saw a website that showed how to make the mashed potatoes the day before.
Since it is my job this year to make to different pies, the stuffing and the yams, I am doing them all today. We'll see if that frees up time for tomorrow. Tomorrow I have to help cook the turkey (19 lbs.) at my friend's house, so I'll be glad to do my cooking today.
