This is one of my all time favorite pasta dishes. It came from one of my mom's old cookbooks, although I have made a couple tweaks here and there over the years. I know Boursin is a little more expensive but if you can help it, don't use the inexpensive imitation brands. The sauce just won't come out right. I have used the low fat Boursin and it works fine. In a pinch, the alouette brand will work, or you can try subbing goat cheese made with garlic and herbs. For a really big meal, add in some chicken, either grilled, rotisserie or just leftover! As a note, this isn't the best dish to reheat so keep that in mind.
