Green bean salad is a refreshing and healthy side dish that is perfect for summer. To make this dish, blanch your green beans in boiling water for 2-3 minutes, then transfer them to a bowl of ice water to stop the cooking process. Drain the green beans and toss them with cherry tomatoes, sliced red onion, crumbled feta cheese, and a simple vinaigrette made with olive oil, red wine vinegar, Dijon mustard, and honey. Serve chilled and enjoy!
