Well, this is not traditional with the typical crust topping, but really good. I guess this was my version of just using up some leftovers from Thanksgiving is where it all started. But I also use chicken or even shrimp. I prefer to serve this in individual serving dishes is you have them, if not, you can use a regular casserole style dish. And I use what I have on hand as far as vegetables go, but feel free to add other vegetables to your liking. These are just what I like best with this. A couple of notes ... creme fraiche is important for this dish; also, I do like to make my potatoes from scratch for this. Serve with a great fresh traditional salad. Iceberg, tomato, cucumber, olives, onions, etc. Very old fashioned comfort food.
