Salt, pepper, and a hot grill pan are all it takes to cook up delicious Pan-Seared Flank Steak.
Heat a grill pan over medium-high heat. Coat pan with cooking spray. Sprinkle flank steak with salt and freshly ground black pepper. Add steak to pan; cook 8 minutes on each side or until desired degree of doneness. Let steak stand 10 minutes; cut steak diagonally across the grain into thin slices.
