Add all ingredients, except the pasta and cheese, to the crock and stir well.

You can brown the beef, pepper and onion in a pan first if you wish (I just chucked it all in lol).

Cook on low for 6 hours, add cooked pasta and grated cheese and serve once the cheese has melted.

Alternatively, sprinkle the grated cheese on top and brown under the grill or in the oven
