Roast some aubergine, peppers, corgettes, mushrooms, onions, and celery in a covered oven dish until they're sofy and easily mushed up - abotu an hour between 150-200. Blitz these up with some pasta sauce, I use Lloyd Grossmans tom and garlic and then USE IT AS THE BASE FOR HOME MADE PIZZAS!!
Made some of this yesterday and made wholemeal pitta bread pizzas and he wolfed them down!
