Place drumsticks, carrots, beans, potatoes and onion in a large saucepan.
Mix tinned tomatoes, water and the Knorr Cream of Chicken Soup powder together.
Pour over the drumsticks and the vegetables. Bring to the boil. Reduce heat and simmer, while covered for about an hour and a half, stirring occasionally, until the turkey is cooked and falling off of the bone. Add more water if needed.
