2. Sprinkle both sides of steak with black pepper. Place steak on a grill rack coated with cooking spray; grill 5 to 6 minutes on each side or until desired degree of doneness. Let stand 3 minutes before slicing.
3. While steak cooks, top tortillas evenly with salad greens and bell pepper. Top with steak slices; drizzle Kickin' Chipotle Spread evenly over steak. Roll up.
