I thought this was great recipe as written. I used some bacon I found at the store called Apple Cider Bacon. It added a nice sweetness to juxtapose the peppery bitterness of the greens. I added what I thought was arugula from my CSA, but it turned out to be dandelion greens - so quite a bit more bitter, but still good. I also used a mixed color cheese tortellini and REAL butter.
