"This is a wonderful recipe and it's easy to prepare. I used fresh spinach that I sauteed in butter with a little minced garlic. Everyone loved these and they're very filling, too."

"I made this recipe for myself, because I have picky eaters, who would never even try something that had the word spinach in it - my husband included. I only made two and surprisingly, my husband ate one of them (after he tasted mine). This was a delicious recipe. I will definitely make it again."

"Hating to waste any food at all (especially in this day and age), I chopped and froze the gills and stems from this recipe for use in future stuffed mushrooom recipes and/or to add to sauces and soups. If making this recipe for dinner, use the chopped stems and gills in an omelet for breakfast along with cheese and fresh tomatoes. I've also discovered that brushing both sides of the mushrooms with olive oil, they can be made up and done on the grill. Delicious!"
