Chop some thick sausages into chunks, gently fry (or grill before chopping).
Gently fry onion/garlic. Add sausages, tinned toms, tin(s) of beans and a couple of tins of broad or borlotti bins and some chopped celery. Bung in the oven for 15-20mins on 180 or so. Serve with garlic bread or big hunks of decent wholemeal, or boiled tatties with butter on. Wash down with lots of red wine. Add crushed chillies when served if that floats your boat. Very easy, very tasty, very filling and makes you fart like Satan's trombone player.
