Mongolian Beef is actually a dish from Taiwan and is often served in Canadian-style Chinese restaurants. Usually made with Flank Steak, this recipe with Beef Rib Finger Meat makes a wonderful and flavourful substitute. Cooking the beef in a pressure cooker means this braise cooks in a fraction of the time. You could also serve this saucy beef over rice noodles, cellophane noodles or ramen noodles instead of rice.
