Classic Mongolian Beef is a popular Chinese dish that features tender strips of beef stir-fried with green onions and a savory sauce. The beef is typically marinated in a mixture of soy sauce, ginger, garlic, and cornstarch to enhance its flavor and tenderness. It is then quickly cooked in a hot wok until it is caramelized and coated in the delicious sauce. This dish is often served over steamed rice and garnished with sesame seeds for added texture and flavor.
