Sautee onion and garlic in olive oil, add some red pepper if you like. Add whatever root veg you might have (potatoes, swede, celariac and carrot here). Chuck in some italian herbs and tomato paste. Add some water/stock and simmer for 10 minutes or so. Tip in cannelloni and butter beans. Simmer gently again. Add in shredded kale.
When kale is cooked - serve, top with grated parmesan or chedder if you fancy.
