Step 1

For the meatballs, preheat oven to 240C. Mix ingredients in a large bowl with your hands to combine, working the mixture so it comes together. Wash your hands, then lightly oil them with vegetable oil and roll pork mixture into walnut-sized balls, flatten slightly and place on a baking tray lined with foil. Roast, turning occasionally, until browned and cooked through (6-8 minutes).

Step 2

Meanwhile, heat oil in a wok or frying pan over medium-high heat, add choy sum and spring onion and stir-fry until choy sum is just wilted (1-2 minutes), add ginger and garlic and stir-fry until fragrant (30 seconds to 1 minute). Stir in hoisin and soy sauces and stock, and warm through. Serve meatballs and greens on steamed rice and top with sliced spring onion.
