Since New Years mean bowl games, we usually have game food which varies (smoked ribs, hot wings, big sub sandwich or make your own sandwich bar, appetizers, chips/dips, etc.). I think the tamales are NYE. We finally found a reliable spot to get good ones. Several years ago, a friend came over and we made over a hundred and froze some that lasted us a while.
Growing up, Christmas Eve dinner was left to dad (I think because mom was tired or bake pies for Christmas or something). He didn’t know how to make much, so we had waffles with all the toppings. Since my wife’s heritage is dutch and her family would occasionally have Aebelskivers (pancake puffs here in the US), we now make those with some sides like bacon/sausage and fruit to blend traditions/heritage. So, breakfast for dinner Christmas Eve.
Other traditions are mostly Christmas Eve - light the luminarias, eat dinner, drive around and see lights, kids (no teen/pre-teen) each have a nativity while I read from the Bible, we sing some carols, new pajamas are opened, and off to bed for the kids while we prep the stockings/unwrapped gifts (so much better than assembling toys when they were little).
