Scrambled eggs and smoked salmon for us.
Not having conventional Christmas dinner. Bought loads of picky bits, duck straws, Indian selection, pigs in blankets, too many to list, we went overboard and have about 15 different ones in fridge and freezer.
Croissants with jam and coffee at about 8:30am. Main Christmas meal around 2:30pm. Cheese and biscuits at tea time, and maybe a piece of Christmas Cake for supper.
