Giant Puffballs are edible wild mushrooms that grow in poor moist soil in the fall. These mushrooms grow abuntantly in my own yard and I never knew they were edible until my friend, who has a knack for edible plants told me so. BE AWARE THAT MANY WILD MUSHROOMS ARE POISONOUS. You should never consume a wild mushroom unless you have confirmed with an expert that they are indeed edible. Puffballs are one of the few unmistakable wild mushrooms, but if they have begun to spore, you canot eat them. FMI: http://americanmushrooms.com/edibles3.htm
My friend Ed and I created this pizza recipe. You can use any of your favorite pizza toppings. This recipe was a great find for me, since mushrooms are virtually carb free, and I am eating a low carb diet.
