Combine all Marinade and Sauce ingredients in medium bowl, mix well. Cover and refrigerate 15 minutes. Combine 1/2 cup marinade and beef Sirloin Steak in food-safe plastic bag; turn to coat. Close bag securely and marinate in refrigerator at 15 minutes to 2 hours.
Remove beef from marinade, discard marinade. Pat dry with paper towel. Place steak in center of grid over medium, ash-covered coals.

Heat oil in wok over medium-high heat until hot. Add garlic and ginger; stir-fry 1 minute, stirring often. Add bok choy, cabbage, pepper, mushrooms and onions; stir-fry 2 minutes until crisp-tender. Add noodles; stir-fry 2 minutes. Stir in remaining Sauce; toss to glaze vegetables mixture. Add 1 to 2 tablespoons of water if sauce is thick.
Divide vegetable mixture between 4 bowls. Thinly slice steak against the grain. Top vegetable mixture with steak. Garnish with onions, cilantro, kimchi and pickles, as desired.
