Add the mince in batches and brown it through. About 5 minutes.
Add the browned mince and all the rest of the ingredients into your slow cooker. Stir well.
Cook on low power for 5 - 6 hours or on high for 2 – 3 hours. Season to taste. If you need to thicken the sauce leave the lid off for the final hour of cooking.
Serve over cooked spaghetti topped with grated parmesan cheese.
