Another sausage n beans maker here - I often use this for any barbecue leftovers too. Fry an onion or two (the more onions that go in, the sweeter the dish will be), then throw cooked chopped sausages (or leftover patties, steak, etc, chopped), 2 or 3 small cans of chopped tomatoes, some mixed herbs, a good heavy slug of worcestershire sauce, bit of tomato paste and some beef stock powder, then simmer for a while until the tomato flavour turns rich. Then add as many cans of beans as you fancy - I often throw a can each of cannellini and kidney beans in. Serve with rice or mashed taters because it has quite a rich flavour.

I tend to add cannellinis in to most of my chicken based casseroles and kidney beans into my beef/lamb ones.
