Start by cooking your chicken breasts. I cooked mine with Sous Vide according to my recipe you can find here. Once the chicken is done cooking you start making your sauce.
Pour all ingredients into a small sauce pan and bring to a boil. Let simmer until the sauce thickens.
Heat the olive oil/butter in a skillet on high heat. Add the frozen yellow beans and stir fry 5-10 minutes or until golden.
