Green bean salad is a refreshing and healthy dish that is perfect for summer. To make this salad, you will need fresh green beans, cherry tomatoes, red onion, feta cheese, and a simple vinaigrette made with olive oil, lemon juice, and Dijon mustard. Start by blanching the green beans in boiling water for a few minutes, then shock them in ice water to stop the cooking process. Toss the green beans with the cherry tomatoes, red onion, and crumbled feta cheese, then drizzle with the vinaigrette. This salad is perfect for a light lunch or as a side dish for grilled meats.
