Season the chicken portions.
Heat a roasting tin or casserole on the hob and add 2 tsp olive oil and place the chicken skin side down. Leave it untouched for a good 5 minutes so that the skin crisps.
Set aside. Add the bacon to the pan, let it colour then add the leeks, thyme and garlic. Soften for a few minutes then stir in the flour.
Add a splash of wine stirring to remove any flour lumps, then pour in the stock.
Add the beans and return the chicken to the pan so that the skin sits proud.
Transfer to an oven (200, 180 fan) for 35 minutes.
