Heat the sesame oil in a sauté pan over medium heat. Add the green beans, crushed red pepper flakes, and freshly cracked black pepper, to taste. Cook, stirring occasionally, for 4-5 minutes or until crisp-tender and vibrant green. Add the minced garlic, and cook, stirring constantly, for 1 minute. Add the soy sauce and stir to evenly coat the green beans. Sprinkle the tops with toasted sesame seeds. Serve & enjoy.
