Step 1: In a medium shallow dish, combine teriyaki marinade, onion, honey, orange juice, oil, garlic and pepper to taste; whisk until blended. Reserve 1 cup for basting.
Step 2: With sharp knife, lightly score both sides of flank steak in a crisscross pattern. Place steak in marinade dish, turning to coat. Cover with plastic wrap and marinate in refrigerator 30 minutes, turning once.
Step 3: Remove steak from marinade; discard marinade. Place steak on grid over medium, ash-covered coals. Grill, uncovered, 17 to 21 minutes from medium rare to medium doneness, basting occasionally with reserved marinade and turning once.
Step 4: Place remaining basting marinade in small saucepan; place on grid of grill and bring to a boil. Meanwhile, carve steak diagonally across the grain into thin slices; arrange on platter. Spoon hot marinade over beef, as desired. Garnish with orange slices and rosemary sprigs.
