In 10-inch nonstick skillet, heat oil over medium-high heat. Add steak; cook 4 to 6 minutes or until deep brown on first side. Turn steak; reduce heat to medium, and cook 4 to 6 minutes or until cooked to desired temperature (145°F for medium-rare). Transfer to cutting board; let stand 5 minutes, then thinly slice. Cover with foil to keep warm.
