This appetizer puts a little spin on the regular stuffed mushroom.

Top Review by KatieNana

These were okay, but I wasn't crazy about the texture with the chicken nearly minced up from the food processor. I also thought it was a little too rich with all of the butter. I was the only one who would eat them, so I won't make them again.
