Whisk well the sauce mix in a small bowl. Set aside.
Heat 2 tbsp oil in a pan or wok over high heat. Add the beans and cook, stir about 7-10 mins or until crispy and browned. Transfer to a large plate.
Add another ⅓ tbsp oil to the pan or wok. Add shiitake mushrooms and cook, stir occasionally for 3-4 mins until slightly browned. Reduce to medium heat, add Lee Kum Kee Minced Garlic and minced ginger, and stir-fry for 20 secs. Return the beans to the wok and add the sauce mix. Toss and cook until the sauce thickens slightly, and the vegetables are evenly coated.
