In a large skillet over medium-high heat, heat the oil. Add the green beans and toss. Let cook 1-2 minutes then add the garlic, ginger, and chili flakes. When the green beans begin to brown, add the soy sauce and scallions. Mix and cook 1-2 more minutes, until most of the soy sauce has been absorbed.
To garnish, sprinkle with sesame seeds or extra slices of scallions.
