This was a great recipe! I only changed a couple things.. I used a Parmesan/Asiago/Romano cheese blend instead of just Parmesan. Also, instead of non-stick cooking spray for baking, I used a high-quality olive oil (the one I used from Olivier & Co. had notes of black pepper and artichoke, called Valdesano). For a red sauce, I used "Spicy Tomato Sauce" from epicurious.com (with twice the red wine) and served it all over spinach fettucini. WOW.
