I tried this recipe from Jane Brody's "Good Food Gourmet" for Thanksgiving last year and my family really loved it!
Steam beans for 5 to 7 minutes or until tender crisp. Rinse briefly under cold water to preserve color, but do not chill. Cover and keep warm. In a large bowl, combine garlic and remaining ingredients. Add warm green beans and toss until well coated. If desired, you can reheat in microwave before serving. If you don't want such a strong flavor of garlic, simmer the unpeeled cloves of garlic in a cup of water for 5 minutes before peeling and mincing. I don't think the original recipe is too strong though.
