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.

Chef's Tip
To thinly slice beef, freeze until well-chilled and very firm but not frozen.
Serve over cooked rice or as a noodle bowl with cooked udon, chow mein, or vermicelli noodles. Alternatively, prepare four portions and serve as a family-style dish on a single platter.
