Mushroom Tetrazzini

I tried Giada's recipe, leaving out the chicken to make this vegetarian.  It was a little bland, but some salt and pepper made it okay.

I thought I had a package of sliced button mushrooms as well as the portabellas, but I couldn't find them, so it was a little skimpy.  On the other hand, I wanted to use up some ice cream ingredients (cream and half-and-half) so I made the sauce from them, which made it nice and rich.  I switched out linguine with whole-wheat spaghetti (the protein kind).  Given the nutmeg in the recipe and the sweetness of the noodles, this made some people think it smelled like dessert.
