Loco Moco

With tender seasoned hamburger patties draped in mushroom pan-gravy, Loco Moco is classic Hawaiian comfort food that's as delicious as it is satisfying. My simple gravy uses pan drippings and caramelized mushrooms to load it up with umami, and it can even be packed into a bento box lunch.
