Beef with Black Pepper Sauce (Hei Hu Jiao Niu Rou)

By most accounts, this dish is of Cantonese origin. The key ingredients are sliced beef, onion, garlic, ginger, and bell peppers seasoned with soy sauce, oyster sauce, Worcestershire sauce, sesame oil, rice wine, sugar, and a generous amount of cracked black pepper. I took a cue from Bee Yin Low's version in her cookbook Easy Chinese Recipes and added some Maggi Sauce to the marinade. Delicious served over steamed white rice!
