This is what I do...
150ml warm water
1 tbsp olive oil
half a sachet yeast
225g strong white bread flour
Mix the flour and yeast, then add the water and oil. Mix to a dough and need until you have a smooth, elastic dough. pop into a large oiled bowl, cover with cling and leave in a warm place for about an hour until doubled in size.
Roll out into one large or two small pizzas then prick all over with a fork.
Top with toppings and bake at 220 degrees for 12-15 mins.
Tomato sauce
soften an onion and 2 garlic cloves in a tbsp of olive oil.
Add a tin of tomatoes and a tbsp of tomato puree, season and simmer for about 20 mins.
