I used love this recipe, but made a few changes. Instead of using processed potatoes, I used yams and changed the cheese to jalapeño havarti. It was fabulous. Thanks for posting the recipe!

I liked this. I pretty much followed the recipe except I forgot to buy the pepper. It still came out good. The scallions are a nice touch

I loved it! The only adjustments I'd make next time: would likely be better with real mashed potatoes. Also bacon would be an excellent addition.

Great idea but I made some changes as well. I made homemade mashed potatoes, stuffed the mushrooms and then put them on the grill for 15 minutes. Turned out awesome!

We enjoyed this... I used the loaded mashed potatoes I had them on hand did sautéed the yellow peppers left out the extra cheese and scallions

I used this recipe as a base and tailored it to my taste. Used Bob Evans potatoes, salmon, Thai chilis, and parmesan cheese since that's what I had. Delicious.

Made this for my newly vegetarian daughter and she loved it!! We will definitely make this again!

I will definitely make it again. My husband loves Potatoes & I love Mushrooms...what more can I say? I believe in following someone's recipe exactly for the first time & then make my changes ...
