Spray a large saucepan with low calorie cooking spray and brown the meat for 5 minutes. Add all of the veg and herbs and cook on a low heat for 5 minutes.
Stir in the tomato purée and cook out for a couple of minutes. Add the remaining ingredients and stir well. Simmer on a low heat for 30 minutes, stirring occasionally, until the sauce is thick and rich, and the meat tender.
