To make the filling, combine all of the filling ingredients in a large bowl.
Place 1 heaped teaspoons of filling in the centre of a wonton wrapper. Dip your index finger in a bowl of water and trace the edges of the wrapper with it.
Fold the wonton in half to form a rectangle shape.
Bring the two bottom corners together. Add a drop of water to those edges and press to seal. Repeat with the remaining filling and wrappers.
Bring a pot of water to the boil.
Mix all the sauce ingredients in a small bowl and set aside.
Cook the wontons on a low boil for 4 minutes or until cooked through. Drain.
Serve the dumplings topped with sauce and spring onions.
