How to Make It
Heat a cast-iron skillet over medium-high heat. Coat steaks with cooking spray. Add to pan. Cook 2 minutes on each side or until desired degree of doneness. Remove from pan; let stand 5 minutes. Cut steaks into thin slices.
Place 2 cups lettuce on each of 2 large plates. Sprinkle each serving with 1/4 cup onion slices. Arrange 6 tomato wedges and 1 sliced steak on each salad; drizzle Blue Cheese Dressing evenly over salads. Sprinkle evenly with pepper.
