There are a few potato flans floating out there and many options for yams. However, I wanted to create something that not only could serve as a side dish but also as an interesting main. We had a couple of pounds of beets and some organic yams and used them to make a beautifully layered flan. I love the richness of both of these vegetables and as the fall starts to roll in, this really feels like the perfect comfort food for a cozy night at home. This meal can easily be converted into a healthy vegetarian main by omitting the pancetta. This turned out great and we had a few days of lunches out it as well.
