This had really great flavor! I cut the recipe in half, and still got plenty for two dinners, with leftovers for lunch (we only tend to eat one piece of chicken at a meal). I used chicken broth in the polenta, and finished it with parmesan cheese. I didn't have any zucchini, so I substituted orange bell pepper and large chucks of onion, which we thought were great. Next time I think I'll add artichoke hearts as well. Our only complaint about this recipe was that the sauce ended up being too liquidy. The tomatoes basically disintegrated, leaving a lot of flavor, but no substance, and we would have liked this a bit more chunky. Overall, very good, and I'll definitely make again. Thanks for posting!
