The tiniest drizzle of nutty sesame oil is all it takes to transform these beans into something really special. Just make sure you are using toasted sesame oil, as regular sesame oil has no flavor. Supermarkets typically stock small bottles of the mahogany brown oil next to the soy sauce or in the Asian or international foods sections.
Combine the soy sauce, water, ginger and garlic in the 3.5 Quart Sauté Pan. Bring to a simmer over medium heat and cook for about 3 minutes, stirring occasionally, until the aromatics begin to soften.
Stir in the green beans. Cover and cook until steam begins to escape from under the lid, about 5 minutes.
Spin the lid to engage the Vapor Seal then immediately reduce the heat to low and cook for about 6 minutes until the beans are just tender.
Remove the pan from the heat and drizzle the toasted sesame oil over the beans. Stir to coat.
