Greek Cheesesteak Casserole

Tonight’s dinner was inspired by a confluence of several factors. And yes, that tends to happen a lot.
1. There was some leftover steak and sauteed onions for a cheesesteak, but no more rolls and not enough for a whole meal.
2. A recent Facebook discussion on mashed cauliflower and turnips
3. My Greek lunch the other day of moussaka and pasticcio.
