Stir the stock, garlic, rosemary, thyme, black pepper, potatoes and green beans in the skillet and heat to a boil. Cook for 5 minutes.
Reduce the heat to low. Return the chicken to the skillet. Cover and cook for 10 minutes or until the chicken is cooked through and the potatoes are tender. Season as desired.
