Marinade Steak: Mix cilantro tamarind paste, soy sauce, ginger, orange zest and juice, lime zest and juice, scallions, garlic honey, chile and fish sauce together. In a large ziplock bag, place the steak and half the marinade. Allow steak to marinade for 30 minutes at room temperature or, preferably, in the refrigerator overnight. Set the remaining half of the marinade aside for serving. Cook Steak: Preheat grill. Grill steak 3-4 minutes per side over medium heat. Remove from grill and cover loosely with foil to keep warm. Allow to rest 5 minutes before slicing. To Serve: Thinly slice on the diagonal against the grain. Make up a platter with the meat slices, carrots, bean sprouts and other desired garnishes. If desired, toss cellophane noodles with reserved marinade or rice vinegar sweetened to taste with a little sugar. Pass remaining marinade for additional garnish. Serve with lettuce leaves and enjoy!
