Though there are many delicious beef dishes in Chinese cuisine, my favorite is stir-fried beef with peppers and onions.  The beef is first marinated in a mixture of soy sauce, rice wine vinegar, and Shaoxing wine. Then, it is quickly cooked in a hot wok with oil, garlic, and ginger.  The peppers and onions are added next, and the whole dish is stirred until everything is evenly cooked.  Then finished with a touch of sugar and a dash of sesame oil. The result is a tender, flavorful dish that will please any appetite.
