I agree with many other reviewers that this recipe comes out remarkably bland. I made a few alterations, per other reviewers' tips, like adding tomato paste to thicken the sauce and parmesan for more flavor. Still, the result was underwhelming, to say the least. It's definitely promising -- the mushrooms picked up the garlic and onion flavors nicely, for example -- but it needs a thing or two more. Next time, I'll try adding sausage, as others have suggested.
