In a bowl, mix the flour, oil, baking powder, salt and pepper and then add the water (add a little more water/flour if needed).
Mix to form a dough and knead for 2-3 minutes so that it comes together.
On a floured chopping board, roll out the dough.
Divide into four and then roll into balls.
Roll the first ball out to a small circle.
Place a few tsps of the spinach filling in the middle and carefully fold the dough over the filing by pressing the edges together. You can crimp if desired.
Place on a greased baking tray.
Roll out the next dough ball following the same method as before and fill with a few tsps of the cauliflower filling.
Repeat until all the dough is filled and placed on a baking tray.
Bake for 15 minutes on a medium heat until slightly crispy on the outside.
