I have just eaten this and it was yummy!
So, after cooking a roast chicken for lunch, this was what I did...
Firstly, simmer the carcass and some of the meat with bay leaves, onion, celery and carrot, add salt and pepper.
Next day I spooned off some of the stock and froze it.
The rest of it I added to chopped potatoes and carrots, added a tin of tomatoes, a tin of kidney beans, some red wine and a bit of tomato purée. Added some of the good meat I'd cut off the carcass, put in oven in a casserole dish, gas mark 4, for about 2 and a half hours. There's probably enough to feed 4-6 people. Delicious!
