This light and refreshing green bean salad is a perfect side dish for summer barbecues and picnics. The green beans are blanched until tender-crisp, then tossed with a simple dressing made with lemon juice, olive oil, and grated Parmesan cheese. The salad is finished with a sprinkle of chopped fresh parsley and a pinch of salt and pepper. The bright flavors of lemon and Parmesan complement the fresh green beans perfectly, making this salad a crowd-pleaser.
