For the past three years, we've skipped the airport crowds and just stayed here in San Diego for the holidays. Last year, my parents were here, but this year it's just us again. (My brother and sister-in-law arrive here on Christmas day.)
For Christmas Eve, we like to stay in and watch a Christmas movie while feasting on a smorgasbord of very simple hors d'oeuvre's. It's easy, and we love it, and it's a tradition.
Our smorgasbord usually includes all or some of the following:
olives, black and green
roasted red peppers
crackers and hummus
chips and salsa
