WOW Mashed Potato Recipe

Q:

My family loves mashed potatoes so we often serve two versions at Thanksgiving, a traditional or simple mashed potato and one other. Any suggestions on something that could be a WOW mashed potato recipe?

A:

When you said WOW, my mind immediately went to a special catering mashed potato recipe that includes mushrooms and onions. This is one to try, mashed potato topped mushroom pie.
