So I made this tonight for my first time. I'd read that another person added garlic powder and nutmeg to the filling, so I did that as well, only adding about half the amt of nutmeg that he/she did. Well, that was a mistake. My husband wouldn't hardly eat it b/c of the nutmeg. I wouldn't have minded a "subtle" taste of it, but it was too overpowering and made it too rich.
OTHER THAN THAT, it was a pretty good dish. I also added some thyme which I think was probably ok. It was quite easy to make and seemed to taste like a traditional pot pie except for the nutmeg, of course. I will definitely try it again (next time omitting the nutmeg!) and hopefully it will be more of a hit with my husband.
