That is so general, and there are so many good menus. I think it depends on how many people, tradition, and personality.
My family on my mother's side does a large potluck dinner on Christmas Eve, with tamales, beans and rice as the things we can count on, and then whatever everyone brings for potluck to go with it.
When I do Christmas Eve at home, we make a variety of appetizers and fingerfoods this would be a menu for us at home:
Baby Burritos with guacamole and salsa
Tortilla roll ups
Mini Sausages in BBQ Sauce
Spinach Artichoke Dip
Broccoli Cheese Dip
Cheeseball with crackers
Hummus with mushroom topping and pitas
We just put it out a little at a time, and nibble all evening.
