I've made this twice. Both times followed the recipe almost exactly (added a full cup of mushrooms instead of 1/2) It's delicious. Both teen boys loved it too. Even the eldest who usually pushes ground hamburger off to the side!
Wow! I am totally blown away at how good this was. I used lean ground turkey (which made it a little dry but still GREAT) and non-fat sour cream and milk. I also did not use mushrooms, as we don't like them. Instead of mixing, I layered the meat and potatoes. This was so easy and just delicious! Thank you!
