Finely chop the prawn meat as well and add to the spinach along with the remaining filling ingredients and mix well.

Cut the dough into approx. 20 small pieces and using more cauliflower flour mix, roll them with a rolling pin to approx. 9cm circles then use a cutter or lid to cut into a smooth circle.
Repeat and stack the dumpling dough circles up using a little flour each time to roll so nothing sticks. You can re roll excess dough.
Working with three at a time, lay out the dumpling wrappers and place approx. 1 tbsp filling into the middle of the wrappers then wet the edge.
