Brown the Italian sausage in a large pan – as its browning, break it apart with a mixing spoon.
Put the browned sausage into the slow cooker, followed by the tomatoes and basil.
Pour the sauces into the slow cooker. Put 2 tablespoons of white wine in each of the empty jars. Close the jars and shake well. Then pour the sauce/white wine mixture into the slow cooker. Stir well.
Cook on high for 3 hours.
Stir and then put the pasta into the slow cooker. Stir well – the slow cooker will be very full at this time. Cook on low for 30 minutes, or until the pasta is fully cooked.
Turn off the slow cooker and pour the fresh Parmesan cheese into the pasta. Mix well and serve with fresh basil as a garnish.
