Creamy Pesto Chicken With Roasted Tomatoes

I suppose the photo below was sort of a note to self: NEVER cook raw beans EVER AGAIN!!! At the Farmer's Market a few weeks back, I was so excited to find fresh Cranberry Beans. Once home, I shelled, boiled, then sauteed in olive oil, garlic, and herbs. Once to what I thought was a good point, I added mushrooms and tomatoes, cooking until softened. Now, I think since MOST of my kitchen attempts come out very well (modestly speaking, naturally), I might - at times - get a little over confident. This was one of those occasions. Good idea, but the beans were not cooked. They were vile. If I do say so myself. Do you know how to cook fresh beans? If so, please do share. My ego is bruised and I am determined to master the art of cooking fresh beans.
