Whip up an easy Asian inspired marinade for Flank Steak using teriyaki sauce, peanut butter and ginger. Serve the steak with a chilled noodle salad.
Combine marinade ingredients in glass measuring cup, whisking until just blended. Cover and refrigerate 2/3 cup for dressing. Place beef steak and remaining marinade in plastic bag; turn steak to coat. Close bag securely and marinate in refrigerator 6 hours or as long as overnight, turning occasionally.
Cook pasta according to package directions, adding broccoli, bell pepper and carrot during last 3 minutes of cooking; drain. Place pasta mixture in large serving bowl. Stir in basil. Heat reserved 2/3 cup dressing in microwave on HIGH 30 to 60 seconds or until hot, stirring once. Add to pasta mixture, tossing to combine. Set aside.
Meanwhile, remove steak from marinade; discard marinade. Place steak on grid over medium, ash-covered coals. Grill, covered, 11 to 16 minutes (over medium heat on preheated gas grill, 16 to 21 minutes) for medium rare (145°F) to medium (160°F) doneness, turning occasionally.
Carve steak diagonally across the grain into slices; sprinkle with sesame seeds and green onions, if desired. Serve steak with noodle salad.
