Place the flour, yeast and sugar into a mixing bowl, add 150ml of cold water and 150ml of boiling water to a jug, mix, add the oil and 1 teaspoon salt and pour into the mixing bowl. Combine until a dough forms.
Dust a clean work surface with flour and knead the dough for 10 minutes. Return to the mixing bowl, cover with oiled clingfilm and leave to double in size.
Preheat the oven to 220c or 200c for fan assisted ovens, knock the dough back and knead one last time.
Divide the dough into 2 pieces, shape into balls and flatten. Dust the dough with flour to stop it sticking to the baking tray.
Spread the cream cheese on to the dough, slice the potatoes thinly (around 2mm thick) place on top of the cream cheese a long with the onions and sprinkle with feta. Cook for 16 minutes or until the base is golden brown and serve with spinach.
