Basic Tomato Sauce for pasta

A little olive oil
1 onion, finely chopped
2 - 3 cloves of garlic, crushed
1 can (approx. 400g) tomatoes, chopped
2 Tablespoons of tomato puree
1 or 2 Tablespoons of oregano or mixed herbs
1 cup of veg. stock or water (or even wine, if you like, for a richer sauce)

Fry the onion and garlic in the oil for a few minutes until softened.
Add the tomatoes, puree, stock or water and herbs and simmer gently for about 15 minutes.
That is the basic sauce - you can add anything you like to it.
Any vegetables chopped and added with the tomatoes etc. Soya mince for a more traditional bolognese type sauce. Beans, sweetcorn, peas.
A sweet and sour sauce is easy to make also - add a can of pineapple pieces in pineapple juice and leave out the herbs. A little vinegar is added too.
This is great with beans and vegan sausages chopped up.
