Can be prepared in 45 minutes or less.

Ingredients

　　1/3 cup minced red onion

　　2 teaspoons balsamic or red-wine vinegar

　　1/4 teaspoon salt, or to taste

　　1 tablespoon olive oil

　　1/2 pound green beans, trimmed and cut into thirds

　　5 Kalamata or other brine-cured black olives, pitted and sliced thin

　　In a bowl stir together the onion, the vinegar, the salt, and the oil and let the mixture stand. In a steamer set over boiling water steam the beans, covered, for 7 to 8 minutes, or until they are just tender, add them to the bowl while they are still hot, and toss them well with the olives.
