Gluten-Free Mongolian Beef is a version of the dish that is suitable for those with gluten sensitivities or celiac disease. The traditional recipe often contains soy sauce, which typically contains gluten. In this gluten-free version, tamari or gluten-free soy sauce is used as a substitute. The rest of the recipe remains the same, with tender beef, green onions, and a savory sauce. Serve this gluten-free Mongolian beef over rice or gluten-free noodles for a satisfying and safe meal.
