We lived 100 miles away, so we never did Christmas Eve there. I have no idea if they did the feast of the seven fishes, although I know my grandma loved eels at Christmas time (and she could have every last one of them, as far as I'm concerned!).
My mom would get mad that the Italian side would kind of "take over" all the holidays, but her French-Canadian family never did much. She did occasionally make pork pie and galumpkies (I'm probably spelling that wrong--stuffed cabbage). And no Dunks, more's the pity.
