WOW!  Just saw this featured in the Oregon Harvest for Schools video for turnips and it looks sooooo good I had to try it.  SUCH an easy recipe, so fast to prep and it lived up to the video and tasted amazing.  I didn't have turnips so I only used potatoes, and also I had to try a different cheese as we were out of Parm.  All good and the leftovers tasted even more flavorful!
