Every Christmas Eve for the past 27 years (that's how long my DH and I have been married), we've had pizza for dinner. The first Christmas we were married, we were leaving early on Christmas morning to spend a few days with my folks. My DH and I decided to celebrate our Christmas on Christmas Eve, but didn't want to have a big dinner with lots of leftovers that would just sit in the fridge and then get thrown away. So, we got a pizza and took the leftovers for lunch along the way to my folks on Christmas Day. It's rather quirky, but it's our special tradition!
