Remove from oven; cover and keep warm.

4. To prepare steak, let steak stand at room temperature for 15 minutes. Combine 1/4 teaspoon salt and next 8 ingredients (through 1/8 teaspoon black pepper); sprinkle both sides of steak with spice blend. Place steak on a broiler pan coated with cooking spray; broil 6 minutes on each side or until desired degree of doneness. Cover and let rest 5 minutes. Cut steak diagonally across grain into thin slices.

Arrange 1 cup kale and 3 ounces steak on each of 4 plates; divide frites evenly among servings.
