We're Italian like Gina and for us Christmas Eve is a bigger holiday than Christmas Day. It's also my Birthday.
We usually have for appetizers
shrimp cocktail
crab dip
steamed little neck clams
Pre dinner
Baked clams and shrimp oreganato
maybe filet
Main course
We used to have linguini with red fish gravy (sauce) and in it was clams, shrimp, calamari, slipper lobster tails and scallops. No one was ever able to eat this much so now for the main meal I make shrimp and scallop scampi over linguini.
Dessert is the usual cheescake and I make Christmas cookies etc.
Christmas Day we usually have some sort of pork roast like a fresh ham.
