Place a large pot of salted water to boil. When it comes to a boil, add the green beans, return to a boil, and cook for 3-5 minutes or until the beans break easily and are tender inside but still have a good bite to them. Strain the beans and place in cold, preferably iced, water so they don't cook any more.
Place extra virgin olive oil and garlic in a wok or large skillet. Sauté over medium-low heat until the garlic becomes very aromatic and colors lightly. Add the red pepper flakes and sesame seeds to the wok, stir-fry for a minute. Then add the herbs and mix.
Add blanched green beans (all water drained) to the wok or skillet. Add salt to taste and, if you wish, a dash of ground black pepper. Use a pair of tongs to mix the green beans with the herbs and sesame seeds so all the beans are evenly coated. Let the beans warm through, then turn off heat.
