This Green Bean and Walnut Salad is a refreshing and nutritious dish that combines the crunchiness of green beans with the richness of walnuts. The beans are blanched to retain their vibrant color and crisp texture, then tossed with a tangy vinaigrette dressing. The addition of toasted walnuts adds a delightful nutty flavor and a satisfying crunch. This salad is perfect as a side dish or a light lunch, and it can be served chilled or at room temperature.
