Cut beef across the grain into 12 (1- to 1 1/2-inch) strips, about 1/4-inch thick. Weave strips onto skewers, and place in a 13- x 9-inch baking dish or shallow roasting pan.
Combine soy sauce, honey, coriander, and turmeric, if desired; brush on both sides of skewers. Cover, and marinate in refrigerator 1 to 4 hours.
Preheat grill to high heat (400 to 450).
Remove skewers from marinade, discarding marinade. Grill 2 to 3 minutes on each side.
