For black bean sauce: Heat a wok or heavy skillet over medium-high heat. Add the oil, black beans and garlic. Stir-fry for 30 seconds. Add the chicken stock, soy sauce, rice wine, and sugar. Bring mixture to a boil stirring often. Mix cornstarch with water to create a slurry. Add to mixture and stir until sauce thickens.
For Mongolian Ginger Beef: Combine soy sauce, chopped garlic, sesame oil and black pepper in a large mixing bowl and whisk together. Slice flank steak on a bias, approximately 1/8-inch thick. Add to marinade, cover, and refrigerate for a minimum of 2 hours.
Lightly oil Mongolian grill or wok. Grill the beef for 2 minutes. Add the peppers, onions, and broccoli. Continue cooking for 1 to 2 minutes until beef is cooked throughout. Add sauce and toss with beef mixture. Coat well and remove from heat. Garnish beef with green onion straws and serve with steamed jasmine rice.
Fermented black beans and rice wine are readily available in Asian markets.
