Self Indulgent Editorial Note:
There is enough
food in the world to feed
100 billion people
(scarcity mentality has been drummed into us all, snap out of it!) Millions of pounds of mediocre tasting mushrooms are waiting to be harvested, flavored, seasoned and appreciated. Let's feed ourselves and the poor, whilst thumbing our nose at the fascist food cartels. Death to the existing order.
