Cook the squash in boiling water for about 10 minutes or until tender, drain and allow to cool.
Place the chickpeas in a large bowl and add the squash, crush with a potato masher or fork then stir in the Walnuts, flour and parsley, season and mix well. Divide into 4 small burgers.
Line the air fryer tray with baking parchment and add the burgers. Air fry for 15 minutes at 180oC until golden. Remove and add the pittas. Air fry for 2-3 minutes to toast.
Split the pittas open, fill with some salad and top with the burgers and a dollop of yogurt to serve.
