Rosies Chicken Soup

Roast chicken for Sunday lunch, but what would you do with the bones or any left over vegetables? A lot of people would throw them in the bin, such a waste! My chickens have had a good life at Half Acre Farm, they deserve to be put to good use.
Fry a chopped onion, a carrot and a garlic clove in a saucepan, fry till the onion is soft, add your chicken carcass and water ( I cheat and add a chicken stock cube as well) and a diced potato, add a little dried coriander and bring to the boil and simmer till the potato is cooked, remove the carcass and strip any bits of meat and put the meat into the soup, add any vegetables (if any, but I wouldn't add sprouts!) left over from the roast, blend then adjust the seasoning. Simple warming soup,
