Ok girls, I need your recommendations for some GREAT appetizers!

So somehow DH and I got suckered in to hosting Christmas at our house this year. Being that there is going to be 13 people, I couldn't do a sit-down dinner because of lack of table space. So when I was talking with my aunt about what dishes to have, she half-jokingly/half-seriously suggested serving just all appetizers. And since it wasn't going to be a sit-down dinner anyway, I thought that it was a good idea.

So now......I am drawing a blank on ideas for appetizers! I could definitely use your recommendations for some fairly easy, can pretty much satisy everyone's appetites, and obviously delicious appetizers! Help!
