Trim ends of the green beans and then cut each one in half. Whisk together soy sauce, peanut oil, and sesame oil to make the cooking sauce. Put beans in a bowl and toss beans with the sauce until every bean is well-coated with sauce. Use a slotted spoon to put the beans in the Air Fryer basket, leaving the extra sauce in the bowl. Preheat Air Fryer to 400F/200C if you have a model that needs to be preheated. Cook beans for about 10-12 minutes or until they are done to your liking and barely starting to brown. .
