So wait, do Americans have turkey on Christmas too?
Sometimes. Christmas is a less specific menu than Thanksgiving.
For the Italian-Americans like myself, it's more about Christmas Eve and the fish dinner. Christmas Day is just another excuse for a ridiculously huge meal.
Fish on Christmas eve? I have never even heard of that. Are you sure it isn't just a family tradition? I'm not sure why anyone would do that, other than just liking fish, of course.
It is definitely an Italian tradition, I can witness from here... So ProgSnob is keeping the family roots alive... Good job!
I' m fully aligned with him.
An idea of what a classical menu would be here at my place
24th night
Starter marinated tuna/swordfish/salmon and some shrimps
Pasta: tonnarelli (a Roman fresh egg pasta) with tuna sauce
Main: sea bass in salt crust, or turbot in oven with roast potatoes
Dessert: pandoro, or panettone or any other local cake eg pastiera napoletana
wine: Vermentino di Gallura
25th lunch
Starter: fried battered vegetables (artichockes, zucchine, mushrooms, etc)
Tortellini or Passatelli in chicken broth
In some cases (another!) pasta dish, eg tagliatelle with ragout sauce
The above mentioned chicken with vegetables, or lambchops, or whatever other meat you prefer
Wine depends on main, but I would go for a Gewurztraminer from SüdTirol (or Alto Adige how we invaders call it)
Dessert as above
Then grappa or Amaro del Capo and / or Limoncello or Mirto
finally everyone enjoy a huge barrell of baking soda
merry *burp*mas everyone!
