This is wonderful pasta with tons of flavor. It is incorporates a lot of different flavors but is well worth the little bit of extra time to make it. The white beans make for a very hearty creamy flavor along with the pancetta, and then the spinach makes for a great light addition to the pasta. I hope you give this a try.
A good friend of mine gave me a similar recipe a few years ago. Hers had bacon and chicken broth, so I added the wine and pancetta instead. I really enjoy the dish and it is a nice change from the every day pasta.
