For the marinade, in a large resealable plastic bag combine lime juice, soy sauce, lemongrass, garlic, ginger, honey, red pepper flakes and oil. Add steak; seal bag and turn to coat. Refrigerate 15 minutes to 12 hours.
Preheat grill to medium (300°F to 350°F). Remove steak from marinade; discard marinade. Pat steak dry with paper towels, and season with freshly ground black pepper to taste. Grill 10 to 12 minutes per side (145°F for medium-rare) or to desired doneness. Transfer steak to a cutting board; let stand 5 minutes. Cut against the grain into thin slices, and serve.
