I don't know how this could have so many ratings and no reviews. I am hesitant to try something with no comments but I did. I made it in a cast iron skillet as in the picture instead of a pie plate as I wasn't sure my plate wouldn't crack under the broiler. 20 minutes wasn't enough time to reduce three cups of broth, and I gave it longer and I still had broth so I ended up with pie soup. It seems like it needed a thickener. As for the variety of veggies suggested, that is going to change the flavor completely depending on what one chooses. I used fennel and parsnips and got a sweet pie. It wasn't unpleasant , but needed something else. Chicken??
