I was just eating another leftover sammie (leftovers of leftovers....) and was thinking about the yam. When I started digging through leftovers to decide what to do yesterday, I kind of questioned the yam, but decided to give it a go - good things can happen when experimenting, and did. It added a really nice flavor element, though one doesn't often think of combining two starches into a single item (or at least, I don't.) But then again, some people actually like potatoe pierogies, so I guess it's not all that unusual. In eating this again, I was glad to have added the yam - YUM!
