Step 1

Preheat the oven to 220C/200C Fan/Gas 7 and put two baking trays in to heat.

Step 2

To make the sauce, put the tomatoes, mixed herbs and sugar in a saucepan. Peel and finely grate the garlic, add it to the pan and set over a medium heat. Simmer gently for 10 minutes until thickened then remove from the heat and season with salt and pepper. Leave to cool.

Step 3

To make the dough, combine the flour, baking powder and salt in a bowl and make a well in the middle. Pour in the yoghurt the stir with a fork to combine. When the mixture forms a rough dough, turn out onto a lightly floured work surface and knead to form a smooth ball. Divide the dough into 4 equal pieces and roll out into thin circles.

Step 4

Carefully remove the hot baking trays from the oven and lay the pizza bases on top. Bake for 3-4 minutes until beginning to rise then remove from the oven.

Step 5

Turn the pizza bases over and top with the sauce. Scatter the mozzarella over the top. Season with black pepper, sprinkle over a pinch of herbs then return to the oven. Bake for 5 minutes until the bases are crisp and the cheese is bubbling.
