Flatiron Steak with Cucumber and Ginger Salad and Black Chile Mayonnaise

In steak sandwiches, the meat is usually paired with onions, cheese, or similarly rich flavors. We wanted something lighter and brighter, something, say, that a person might opt for at lunchtime without needing to nap afterwards. And so we use fresh ginger (which we julienne like a vegetable rather than shred, mince, grate, or sprinkle as a spice) and cucumber, both very refreshing. While Black Chile Mayonnaise (page 177) does add a touch of richness, this is still a very light red meat sandwich.
