Lift the dough onto a lightly oiled baking tray, cover with a piece of oiled cling film and allow to prove in a warm place for about 15 minutes.

Meanwhile, make the sauce. Heat the oil in a pan and add the sliced garlic, fry very gently for 1 minute then add the tomatoes or passata.Heat for about 5 minutes then remove the pieces of garlic and discard. If you use chopped tomatoes then you must mush these up.
