Heat the olive oil in a large saucepan over medium heat. Add the green beans and sauté until just tender, 5 to 7 minutes. Season lightly with salt to taste and remove from the heat.
Combine the soy sauce, tahini, honey, sesame oil, red pepper flakes and garlic in a small bowl and mix until thoroughly combined. Drizzle over the green beans and lightly toss to combine.
