I posted this request and then got buried at work and didn't get back to reply to it, though I did follow some of the excellent suggestions, particularly from pairs4life:

This was more than we could possibly eat, just being four of us! But it was my template, so thank you!
We had a pork roast instead of turkey -- my one mistake was not taking my son up on his offer to cook a pork shoulder; he had only done it twice, once pretty bad, and the second a success -- but I was nervous about it, and not sure we would have the right spices, etc., in the cottage kitchen. Instead I cooked what turned our to be a very boring pork loin roast.
My son did make wonderful biscuits (though he had been napping and I woke him since he had the recipe, and he was a bit dazed, and accidentally doubled the butter, and when we opened the oven to see if the biscuits were done, we both burst out laughing because the biscuits were frying in butter. Nevertheless they were delicious.
I made fabulous collards (with bacon and onions and garlic) -- and then I had to make minestrone soup the next day with the rest of the collards, because the grocery sold them in four pound packages. Yow! This photo is the greens, not the soup, which also had white beans and pasta in it. I don't normally cook with bacon, so although I have cooked collards before, I have never made anything this delicious. I was very pleased.

Sweet potatoes, baked -- candied was too much sugar for us. The boys would have adored macaroni and cheese, but we all agreed it was overkill.
We made plenty of cornbread, but not for this dinner. (My husband has read that you soak up the collard pot liquor with cornbread, so that was lunch the next day.)
We are not big coconut eaters, so we altered the pie to banana cream, which seems southern to me, even if it isn't, and it was excellent. Last time I made banana cream pie (which was the first time I ever made it) it did not set well, and was best eaten with a spoon. This time, it came out just right -- better recipe, I think, something I found on the internet.
It was quite a Christmas feast!
I've posted on the Charleston thread about some of the food we ate when we were not at the cottage. The mix of being able to cook and going out when we wanted to was perfect. The boys and I love puttering around a kitchen together, and it would have been a shame to have missed that as part of the vacation. But we ate some fabulous meals out as well.
