For a light and refreshing side, try this quick and easy Kidney Bean Salad recipe. While green beans and wax beans don't get naming rights, they add wonderful texture (and extra vitamins and fiber) to this bean salad side dish.
In a large bowl, combine wax beans or black beans, green beans or lima beans, red kidney beans, sweet pepper, and red onion.
For dressing, in a screw-top jar, combine vinegar, sugar, oil, celery seeds, dry mustard, and garlic. Cover and shake well. Pour over vegetables; gently stir. Cover and chill for at least 4 hours or up to 24 hours, stirring often.
