Peel and chop the carrots, onions, potatoes and parsnips
Heat the oil and cook the chicken pieces over a high heat for a few minutes, turning to get all sides golden.
Remove chicken from the pan to a plate while you cook the onion in the same oil and heat until soft.
Add the rest of the ingredients including the chicken to the pan, stir well and bring to a simmer. Put the lid on and leave to simmer on a low heat for one and a half hours.
