Healthy Mongolian Beef is a lighter version of the classic dish that is perfect for those who are watching their calorie intake. In this recipe, lean beef is used and cooked with a minimal amount of oil. The sauce is made with reduced-sodium soy sauce, honey or maple syrup as a natural sweetener, and fresh ginger and garlic for added flavor. This healthier version still packs all the delicious flavors of the original dish, but with fewer calories and less fat.
