Mongolian Beef has no connection with traditional Mongolian cuisines but that doesn't stop us from eating this Chinese-American creation. The term Mongolian is meant to imply the food is "exotic". Nevertheless, the dish is tasty and very simple to re-create at home. You may have a harder time convincing your family it's not take out. Now consider this our version of Mongolian Beef, if you are a purist omit the vegetables and add chopped green onions at the end.
