The “feast of seven fishes” is an Italian-American tradition my family celebrates every Christmas Eve. We all get together at my brother's house, they have a huge kitchen island, which we completely cover with several different kinds of fishes, sardines included. We then gather 'round the island to feast and laugh and catch up. The number of seven fishes for the feast is another Christmas mystery with many theories you can read about here. However, my family never sticks to just 7 and some ambitious years we’ve had as many as 18! No matter the number of fish, we always end with my Nonie's tuna gravy and spaghetti. Yummmmm...
