Tomato sauce for pizza

Method

1. Heat the oil in a large sauté pan over a gentle heat. Add the onion and garlic and cook very gently for about 10 minutes until soft – don’t let them brown. Add the remaining ingredients and season. Stir, then simmer for 20 minutes until you have a thickish sauce. If using fresh tomatoes, you will need to break them up with a spoon.
2. This keeps well in the fridge, in a sterilised screw-top jar, for up to a week.
