This turned out great. I had a ton of summer squash and corn to use up from our CSA box plus freshly milled polenta, so this recipe was a must. I cooked the pintos from scratch. I mostly stuck to the recipe, but used oil spray instead of the 3 Tbsp and also used crushed tomatoes. Thanks for posting, we enjoyed this very much.
I made this dish for a native american presentation where I work and the visitors loved it almost as much as my fellow employees. Delicious.
