summer vegetable succotash with basil

My supperdish my succotash wish ... I never really knew what succotash was but, I sure LOVED that song.  I just learned that succotash is a dish that is primarily made from corn and shelled beans.  The dish can be adapted easily and made with seasonal vegetables.  I have played around adding different veggies such as baby Yukon gold potatoes, red bell pepper and okra. They were all good but, the combination below is my favorite.   Black-eyed peas, edamame, or lima beans can be substituted or added.  I love the lightness of this side and the use of so many fresh summer vegetables.  This is so easy to make, pairs well with many summer meals, and the left overs taste great.
