To make the filling, combine all ingredients (except wonton wrappers) in a bowl. Mix together well for about 2 minutes or until the mixture is sticky and very well combined. You can use the mixture immediately to fill your wonton wrappers or cover and chill in the fridge for up to 24 hours.
Fill a small bowl with a some water and set aside. Working with one wrapper at a time, place about 2 teaspoons of filling into the centre of the wonton wrapper. Using a lightly wet finger, dab some water along 2 edges of the wrapper, then fold the wrapper over to form a triangle, pressing to seal. Squeeze gently around the filling to remove any pockets of air.
Dab a little water in the bottom right corner then bring the two corners together and seal to form a diamond shape. Transfer to a lined baking tray and repeat with remaining wrappers and filling. You can either cook the wontons immediately or cover with plastic wrap and freeze until firm. Once firm transfer to a zip-lock bag and freeze until required.
Bring a large saucepan of lightly salted water to the boil. Working in batches, cook the wontons for 4-5 minutes or until they float to the surface and the filling is firm and cooked through. Remove with a slotted spoon or spider and transfer to bowls. Repeat with remaining wontons.
