I saw this on "Everyday Italian" yesterday and really wanted to try it, mainly because I love both mushrooms and asparagus, and have been wanting a recipe to use up some of the mascarpone cheese in our fridge! I liked it a lot, and my husband loved it. I preferred mine without walnuts, so you may want to serve these on the side. It is so quick to make that it's sure to become a regular at our house! Keep in mind, however, that this is a very mild pasta, most likely very different from what you're used to!
