Heres something that should make every home cook happy: theres tons of flavor in less expensive cuts of meat. The trick is to treat those cheap cuts right, as is done in this recipe, where beef stew meat is browned in a skillet and left to finish off over low heat in the slow cooker. The result of this all-day stewing is succulent and fully flavored mongolian beef thats well complemented by its sweet and savory saucemade of brown sugar and soy sauce. The chopped carrots and vinegar added at the end provide a welcome bit of freshness and acid to the dish, while the garnishes of fresh, chopped green onions and sprinkle of sesame seed adds brightness and sweet nuttiness. Serve this with rice, and youve got a take-out favorite dinnerat a fraction of the price.
