Preheat oven to 425 degrees.

Place the green beans on a baking sheet (line with foil for easy clean up.) Drizzle 1-2 tablespoons of olive oil over the vegetables.  Sprinkle with garlic, salt, and pepper.  Toss to coat.

Bake for about 15 minutes, or until tender.  Sometimes I will also preheat the broiler and cook them that way.  Same amount of time.

Place beans in serving bowl and sprinkle sesame seeds over them, toss to coat.
