Picnic Perfect Recipe: Beans have a very long shelf life whether dried or canned. They provide a nice creamy addition to most dishes such as salads or soups. Beans also stay fresh without refrigeration for several hours which is perfect for outdoor picnics or barbeques. For a perfect summertime bean recipe try Corn and Black Bean Salad with Basil-Lime Vinaigrette courtesy of the Food Network. The corn and mango chunks add the perfect sweetness to balance the acidity of the vinaigrette, while the two different types of beans provide all the carbs, protein and fiber you could ever want in a salad. Like always, don't be afraid to customize any recipe to suit your taste.
