Pull the stems off the green beans, if the beans are large pull out the string from the beans. Drop beans in boiling water for 3 to 4 minutes, drain and plunge the beans into ice water. When the beans are cooled, heat olive oil in a skillet. Lightly sauté garlic in heated oil for a few seconds, and then add the green beans, stirring frequently until warm. Serve warm or cold. If you enjoy garlic add a few more cloves, or less if you don't like the flavor of garlic.
