Coat the chicken with flour. Then add the oil to a large non-stick pan, over a medium heat
Add the chicken to the pan, turning until it is sealed and starting to brown. Remove from the pan and set aside
Reduce the heat, add a touch more oil, if needed, and add the shallots, garlic, leeks, carrots and herbs, and cook gently for 5-6 mins, until softened
Return the chicken to the pan, increase the heat slightly
Add the white wine, and Worcestershire sauce and allow to bubble away and reduce for a few mins, before adding the stock
Reduce the heat, cover and cook for 20 mins, before adding the beans
In another pan gently steam the broccoli for around 3-5 mins until al dente
Cook for a further 5 mins, then check if the chicken is cooked by seeing if the juices run clear when pierced with a knife
Scatter over the herbs, and serve up with the broccoli.
