Heat the oil in a large casserole dish over a medium-high heat and cook the onion and garlic for a few mins. Stir in the sausages, breaking them up into small pieces as you go, and cook for another 8-9 mins. Stir in the chopped tomatoes, stock, purée and most of the rosemary. Bring to a simmer and cook for another 8-10 mins or until the mixture is thickened. Season to taste.
