I use chicken thighs, roast them in the oven, then in the slow cooker for 8 hours with celery, onion, carrots, turnip & potatoes, after 4 hours I normally add split peas & lentils & a tin of baked beans. Then lift out all the thighs, allow to cool enough to handle, strip all the meat off, cut in to cubes, put back in slow cooker, season, I normally put a glug of fruity sauce & tomato ketchup, leave for half an hour. The best chicken soup ever, we eat half & freeze the rest.
