Feast of the Seven Fishes
My mother is Italian, so we were raised with many Italian traditions, one of them being on Christmas Eve, we have a feast consisting of 7 different fishes. It's pretty common in the Northeast.
Usually they are spread out over numerous courses, then desserts, and this continues throughout the evening as family and friends come and go. Then you go to midnight Mass.
When I was dating my husband, one Christmas Eve we spent with his family. I never asked what they were making since they raised their family here in New York. They lived 4 hrs away, so when I got there, I found out that we were having a turkey

They also don't like garlic or spices, so I thought I was definitely in he!!.
I cried because I thought it was in the Bible that you were not supposed to eat meat and that you were supposed to have fish.
I called home in tears and told my family that I was celebrating the holiday with hevens.
My now father in law who is a church going man told me that no where in the Bible does it say that one can not have meat on Christmas Eve. I went to midnight mass with him and the other parishoners verified this.
But, I still bring my own fish and some to share whenever I visit his family for the holidays minus the garlic. ;-)
