I find it so interesting that Thanksgiving seems to be the 'major' holiday in the US while I would say that Christmas is tops in Canada. I have really enjoyed reading about your different menus and why they are special/traditional for your families.
As far as holiday menus are concerned, I suppose we have become non-traditionalists. (This may have something to do with trying to cook a 15 lb. turkey on Christmas day in Australia--when the temp outside was +100 and it was hotter inside!!) It can be anything from totally traditional to ordered in Chinese food. Hosts' choice. Makes for some interesting fare.
Enjoy your holiday!
