step 1
Pour the tomatoes, herbs and sugar into a saucepan. Crush the garlic and add it to the pan. Set over a medium heat and simmer gently for 10 minutes.
step 2
Remove from heat, season with salt and pepper and leave to cool.
step 3
Preheat the oven to gas mark 7/ 220c and put 2 baking trays in to heat.
step 4
Combine the flour, baking powder and salt in a bowl and make a well in the centre. Pour in the yoghurt then stir with a fork to form a rough dough.
step 5
Lightly flour your work surface, turn the dough out and knead to form a smooth ball. Divide into four pieces and roll into thin circles. Put the bases on the warm trays.
step 6
Bake for 3-4 minutes, turn the bases over, top with sauce and cheese (and any other toppings you like) and bake for another 5 minutes.
