Though the name would imply that it was created in Europe, it’s actually an L.A. classic. Thin sliced beef, rich and beefy au jus with a little spicy mustard make for an immensely flavorful trio. Add sliced cheese for another rich layer. Look for a crusty French loaf for this recipe, as a baguette is typically too narrow. Pro tip: work quickly when it’s time to build to avoid a sandwich cooling down while building others.
