I first tried this plate in Boston's North End. It is pure comfort food. This is my recipe. The authentic Paglia e Fieno uses half egg noodles and half egg noodles with spinach. I found it difficult to find the spinach egg noodles so I just went with the regular. An alternative that people usually do is half spinach fettucine and half regular fettucine. I prefer the egg noodles for their flavor but either one is okay. Buon Appetito!
