The spice rub for this steak evokes the complex flavor of a rich Mexican mole sauce, but with almost no investment of time. It's great for a weeknight dinner party.
Pat steak dry and season with 3/4 teaspoon salt, then coat with spice mixture. Heat oil in a 12-inch nonstick skillet over medium-high heat until it shimmers, then cook steak, turning once, 8 to 9 minutes for medium-rare.
While steak cooks, wrap tortillas in foil and warm in oven.
Let steak rest 5 minutes on a cutting board, then thinly slice across the grain at an angle.
