Place beans in a steamer basket over boiling water. Cover pan and steam 5 to 7 minutes or until tender. Rinse under cold water to cool. Drain. Melt butter in a heavy nonstick skillet over low heat. Add garlic, cover pan and braise 20 minutes or until garlic softens and is golden. Remove cover and mash garlic until mixed thoroughly with butter. Transfer green beans to skillet and increase heat to medium. Sauté 3 minutes, stirring frequently, until beans are heated throughout. Stir in herbs, salt and pepper to taste.
