Wow, What a feast. Don't you just love it when everyone else is some ethnic group and you are like a sore finger. Preferably the middle one. Being Native American and English, I have been know to just get up and walk out when they start yapping in Italian as if you are blind and not even there.
My daughter stuffs her squid. Have you ever had it? It is a big favorite of Italians. My daughter stuffs hers. I help her clean them getting off the outer skin and removing the glass like piece of plastic that is often called a bone. After that she is on her own. They are a lot of work.
To answer your question, if it is seven products that live in the water, fresh or salt, it is considered Seven Fishes.
