Three Bean Salad
Cut the fresh green beans into 1-inch pieces, then steam and let them cool. Dice the red onion. Whisk the vinegar, oil and salt and pepper together in a bowl with a tight fitting lid, then add the green beans, garbanzo beans, red kidney beans, and onion and seal with the lid. Shake gently to coat the beans and then refrigerate overnight. Serve chilled as a salad or side dish.
