Cook on Christmas Day, that is? I don't, I do get up a little earlier than the rest of the family and make some Sticky Quickies and put a breakfast casserole in the oven. The rest of the day they get left overs from the big meal I prepared for Christmas Eve dinner. Ham or prime rib sandwiches on croissants, salads, and a variety of desserts all left overs. This way I am not stuck in the kitchen and can enjoy the day with the rest of the family.
