Italian tomato sauce

Yet another version of it. This one works for me, and goes well simply with pasta or polenta; it's also lovely used in a lasagne or cannelloni.

1 tbsp olive oil
2 sliced rashers of bacon, trimmed of excess fat
1 onion, chopped
2 cloves of garlic
1 400g can of plum tomatoes, blended in the processor
2 tsp dried oregano
3 tbsp worcestershire sauce
1 tbsp black pepper
1 tsp salt
100ml red or white wine

Heat the oil in a saucepan, and add the bacon, onion and garlic, and when browned put in the rest of the ingredients. Simmer slowly to reduce for about an hour, maybe less - you want to get a thick and rich sauce.
