Put the silken tofu and soy sauce in a tall jug and add 3 tablespoons of the reserved pasta water ... You can use frozen spinach, just make sure it’s completely defrosted first.
Put the dish back into the air fryer and spoon in the pasta, stirring to ensure it is well coated in the sauce. Cook for a further 8 minutes. Scatter over the olives, feta and parsley and mix well.
