Add Boullion Cube, Parsley and Bay leaf then stir, cover with a fitted lid and allow it boil. When it boils, turn the heat on low and let it simmer for 45 minutes.
You may use chicken instead and frozen green beans. If you using both the cooking time will decrease, since chicken does not need as much time as beef. Beef is always better when it cooks more on lower temperature until it starts to fall apart.
