Make the dough. Mix the flour, yeast and salt together in a large bowl. Mix together the sugar and warm water then make a well in the centre of the dry ingredients. Pour the sugar and water into the well. Gradually mix the wet and dry ingredients together and then turn out onto a floured work surface. Knead for 10 minutes. Flour the outside of the ball of dough then place in an oiled bowl. At this stage you can either prove for about 15 minutes somewhere warm or put it into the fridge until you're ready to use.

Make the sauce. Heat the olive oil over a medium heat. Add the onion, garlic, plenty of salt and 40ml of water. Once the water has evaporated pour in the tin of tomatoes and cook down until it's almost dry. Mix in the tomato puree, chilli powder and oregano and leave to cook a little more until it has a thick consistency. Tip out onto a plate and allow to cool.

Divide the dough into two pieces and roll out until about 5mm thick then place on baking trays and leave to rest while you prepare your toppings.

Slice up all your topping ingredients then spread your sauce across the pizza bases. Sprinkle over your toppings followed by the cheese and bake for about 15 minutes. Slice and enjoy!
