At my house, we don't like those fried mushrooms that are black and slimy where the breading slides easily off. This recipe is just a very crisp breading on a fresh mushroom. They'll 'pop' when you cut into them they are so fresh. Panko breadcrumbs are a polished bread crumb that you can find in an Asian market or the International section of your favorite food store and they make just a wonderful crunchier coating, too.
Simple as simple gets, this fabulous smoked turkey club panini has been on the dinner table in our home at least thrice in the last two weeks. Equal parts because it is quick and easy (soccer, baseball season!)
