Thin slices of beefy Flank Steak are marinated and dusted with cornstarch to maximize tenderness and give them their signature silky texture. Stir-fried with sweet onions and peppers, then tossed in a tangy sauce accented with fragrant ground Sichuan peppercorns and Chinese five spice, make this a dish bursting with sweet, spicy, sour and salty flavours.
