Mongolian Beef is a flavorful and tender dish that is sure to satisfy your Chinese food cravings. It is made by stir-frying thinly sliced beef with green onions, garlic, and ginger in a savory sauce. The sauce is made from a combination of soy sauce, hoisin sauce, and brown sugar, which gives it a rich and sweet flavor. The beef is marinated in a mixture of soy sauce, cornstarch, and sesame oil, which helps to tenderize the meat and infuse it with flavor. Mongolian Beef is typically served with steamed rice or noodles, making it a hearty and delicious meal.
