Tuna and Butter Bean Salad

I didn't have butter beans. Neither did the store. It turns out, butter beans are white lima beans. I didn't discover that pertinent fact until after I'd already bought white kidney beans (Cannellini) to use in this recipe. It was fantastic and very quick and easy.

Update: Safeway DOES have butter beans. I found them. They were great with this!
