Put the ribs in a large pan and cover with water. Bring to the boil and simmer for 25 mins.
Drain the ribs very well, then place into a large mixing bowl. Add the Lee Kum Kee Ready Sauce for Kung Pao Chicken and 2 tsp oil into the bowl and mix through to evenly coat the ribs.
Heat the grill to high. Grill the ribs for 15-20 mins, turning from time to time until shiny and slightly charred in places.
Meanwhile, cook the choy sum and bok choy in a steamer over a saucepan of simmering water for 1 min or until the vegetables are bright green. Quickly use tongs to transfer the vegetables to a bowl of iced water to refresh. Drain and then place into a serving dish and sprinkle over the Lee Kum Kee Pure Sesame Oil and Lee Kum Kee Premium Soy Sauce.
If desired, garnish cooked ribs with chilli, spring onion, and sesame seeds. Serve with white rice and steamed choy sum and baby bok choy.
