This is a tomato sauce with all the bells and whistles. I make it in big batches and freeze it in portions for an instant dinner with pasta, or to spread on pizza bases, or for anything which needs a good tomato sauce really. It is also a good place to hide other vegetables which might not be popular served alone. The smoked paprika gives it a wonderful deep flavour.
You can add whatever other vegetables you want during the cooking, depending on how long they take to cook. Courgettes around 20 minutes, spinach just a few minutes.
