I can see why this is one of your favorite meals. This recipe is delicious and will go straight to my keeper file. I took delight in every single bite. I made a couple substitutions based on what I had on hand and I honestly can't imagine the recipe as written tasting any better, but I intend to find out. I used about 3/4 cup thinly sliced leek instead of onion, a combination of grated mozzarella, pepper jack and parmesan cheeses and a 1/4 t. of dried tarragon instead of fresh. So, so good. Thanks so much for posting the recipe.
Outstanding; my wife was moaning while she ate! (Doesn't happen every day). This was easy to prepare and delicious. I used baby portabellas instead of crimini and regular sour cream but otherwise followed exactly. Thank you Hey Jude.
Delish and so easy to make. This is great for a work night meal. I had to make some subs due to my dietary restrictions, including leaving out the oil, and using fat fee sour cream. I also used only about half as much cheese and it was low fat swiss. The tarragon is a fantastic flavor and really makes this dish. Thanks for posting, this is a keeper!
