Now I'm not much into casseroles, just a few, and not a big fan. But this is good. Whole wheat pasta, chicken breasts, fresh crimini mushrooms, olives tossed with a creamy sauce and some extra cheese. Baked and served. After a review, I admit, this is a lighter flavor I admit. This was designed for a friend who doesn't like quite as much spice as me. Two options ... I have made this with 1 1/2 cups or 1 can of green olives to the kalamata which does give a little more salt and flavor. I do use some of the broth as well. Also using whole wheat pasta is a key, and cremini is a key for this recipe. Good parmesan not the green can is again important and fresh basil. This dish really relies on KEY ingredients. But the extra olives will definitely help. But this is a very mild dish with subtle flavors.
