I made a few changes to the recipe, I used parsnips instead of turnips (didn't actually mean to do this, just read the recipe wrong), added 3 slices of bacon that I cut into small pieces and sauteed with the veggies, didn't use the egg whites, and used about half the milk (ran out), also used a sharp cheddar instead of fontina. I thought the flavors were awesome together. The parsnips made it slightly sweet, but went really well with the broccoli rabe. The bacon also added a lot of flavor. Will definitely make again.
Pros: tasty, healthy
Cons: little time consuming
