Make the chicken filling

• Mix the ground chicken with the spring onion, ginger, garlic, soy sauce, sesame oil, cornstarch, salt and white pepper.
• Stir until the filling is well combined and slightly sticky.

Fill the wontons

• Place a small spoonful of filling in the center of each wonton wrapper.
• Wet the edges with water, fold and pinch to seal, pressing out any air.

Simmer the broth

• Bring the chicken stock to a gentle simmer in a pot.
• Season with a little soy sauce and sesame oil.

Cook the wontons

• Slide the wontons into the simmering broth in batches.
• Cook until they float and the filling is cooked through.

Add the greens and serve

• Add the bok choy and simmer until just tender.
• Ladle into bowls and finish with chopped spring onion and a drizzle of sesame oil.
