Thank you all very much!
I now have a plethora of information. Since we have to adhere to the strict fasting rules on Christmas Eve, my family always used to go to a Mexican restaurant to have fish and shrimp (bizarre, I know, but when you live 60 miles north of that border, you are engulfed in the Mexican heritage, which is fine with me because I love it all), or just make shrimp cocktail. But I want a change this year, so when I found out about the Holy Supper (my heritage has traditions for Christmas Eve, but they aren't appropriate for the fast: German, English, Dutch, Swiss, etc...), I was very excited to try to prepare it for my family this year. I'm very certain I can pull off a small and simple version of it. So, thank you again for all your help! May God Bless you and your families as we all prepare for the coming of the Christ Child.
