Step 1

Whisk together the oil, soy sauce, brown sugar, garlic, ginger and pepper in a large bowl. With the tip of a knife, lightly score the surface of the steak in a crisscross pattern. Immerse the steak in the marinade and refrigerate for several hours, turning it over now and then.

Step 2

Prepare a grill. When it is hot, place the steak on the grill, shaking off excess marinade first. Cook roughly 4 minutes on each side for medium rare. Let the steak rest for a few minutes, then slice it thinly, on the diagonal.
