Three bean salad

Bean salad is a common salad composed of various cooked beans—typically green, wax, kidney, and/or lima beans—tossed in a sweet-sour vinaigrette. Variant ingredients include fresh raw onions, bell pepper, and/or other cooked or raw vegetables, such as chickpeas. Bean salad can also be prepared as a pickled dish, making it a popular choice for home canning. Salads prepared with this method should be used within a year for best quality. Cultures around the world have their own version of bean salad. Balela is a Middle Eastern salad that typically uses chickpeas and black beans with tomatoes, herbs, parsley, and lemon juice. South American bean salad features poroto beans with tomatoes, parsley, oil and vinegar, and is served with grilled steak.
