Now heat the oil in a flameproof casserole or saucepan, brown the sausages all round and, using a draining spoon, remove them from the pan.

Next stir the onion, green pepper and garlic into the fat remaining in the pan and cook gently until softened (about 10 minutes). 

Now stir in the remaining ingredients, bring up to simmering point, then return the sausages to the pan. Allow it to simmer very gently, uncovered, stirring occasionally, for about 25 minutes until the tomatoes are reduced to a thick, sauce-like consistency. Then taste and season with salt and pepper before serving.

This is very good with buttered noodles or creamy mashed potato.
