In Italian-American families, many celebrate Christmas Eve with the Feast of the Seven Fishes. Their dinners would include fish in a variety of courses and recipes. One could have antipasta, soup, salad, and main courses consisting of multiple dishes containing fish.
I am not Italian, but I was reminded of this Christmas tradition when I served smoked salmon jerky for lunch and remembered that I was frying fish for dinner tonight. Fish with chips (french fried potatoes) with peas are a popular English meal.
