Fresh green beans are briefly boiled until bright green and crisp-tender, then tossed while still hot with extra-virgin olive oil, red wine vinegar, sliced garlic, salt and black pepper.

Extra-virgin olive oil, red wine vinegar, thinly sliced garlic, salt and pepper create the simple vinaigrette for Green Beans Marianna.
