Quick Tomato Sauce.

This is a quick version of a tomato sauce for pasta dishes etc using tinned tomatoes.
Grate (or finely chop) an onion - add to a sauce pan with olive oil, a clove of chopped garlic and half a chilli. Cooked for a few mins until the onion softens and add a tin of chopped tomatoes.
Add half a tea spoon of sugar and cook on a very low heat for an hour or so until it cooks down into a thick sauce (this also helps to get rid of the tinnyness of the tomatoes).
