Mongolian beef is a dish served in Chinese-American restaurants consisting of sliced beef, typically flank steak, and stir-fried with vegetables in a savory brown sauce, usually made with hoisin sauce, soy sauce, and chili peppers. The beef is commonly paired with scallions or mixed vegetables and is often spicy. The dish is often served over crispy fried cellophane noodles or steamed rice.
The name of this dish is somewhat misleading, as aside from the beef, none of the ingredients or the preparation methods are drawn from traditional Mongolian cuisine. The term "Mongolian" is rather meant to imply an "exotic" type of food.
