Wagyu Katsu Sando


30 m

After so many requests, I made Japan's most famous sandwich: The Wagyu Katsu Sando. This is often called the most expensive sandwich in the world, and for good reason. It can cost up to $200 dollars for just a small sandwich in restaurants, but it's so simple to make. And, if you choose to make this, you can't forget about the sweet, umami katsu sauce to go with it. All I could think about when eating this sandwich was "butter." Yum.
