Boxed in on Boxing Day?

Q: I am invited to an affair called Boxing Day. My Scottish and Polish sister-in-law will be having Scottish and Polish food and I would like to bring a side dish that will knock their socks off. They wanted my spinach salad but I am thinking of Barefoot Contessa's scalloped potato and fennel casserole. ... Are there any other appropriate side dishes for Boxing Day that I can consider bringing? I would like to make some hearty vegetable side dishes such as red cabbage, apples and vinegar.
