Turn Your Filet-O-Fish Into a Fish McFeast: The Norwegian-Style Hack

The piece explains how to upgrade a McDonald's Filet-O-Fish to a Norwegian-style Fish McFeast by adding the same toppings (lettuce, tomato, onion, pickles) and using a DIY McFeast sauce made from ketchup, mustard, and McChicken mayo; to finish, add a splash of vinegar to the condiments at home, since U.S. outlets do not offer McFeast sauce. This can be done via the app or in-store.
