INGREDIENTS

2 pounds fresh green or bush beans, trimmed

½ cup balsamic vinegar

⅓ cup extra-virgin olive oil

1 small sweet onion, thinly sliced

1 clove garlic, minced

2 teaspoons chopped fresh parsley

1 teaspoon white sugar

1 teaspoon salt

freshly ground black pepper to taste

PREPARATION

Bring a large pot with lightly salted water to a boil over high heat. Add beans and cook, uncovered, until soft but still firm to the bite, 7 to 10 minutes. Check often so beans don't overcook.

Combine vinegar, olive oil, onion, garlic, parsley, sugar, salt, and pepper in a large bowl.

Drain cooked green beans and mix with dressing in the bowl while still warm. Allow to marinate at room temperature for at least 1 hour. Serve at room temperature or chilled.
