The new USDA ChooseMyPlate guidelines emphasize more fruits and vegetables at every meal. Although mushrooms aren't really vegetables* (don't tell the Feds, they might kick us out of the club) they do add delicious flavors and satisfying textures to any meal. If you are cutting down on meats, mushrooms also add a savory richness that vegetables just can't match.
*Mushrooms are in the Kingdom of Fungi, not part of the Plant Kingdom. In fact in some ways, mushrooms are biologically more like animals than plants. Our Chef Liaison, Bob Engel. always says, "Mushrooms behave in the kitchen more like meats than vegetables." You can put this to the test by grilling our Trumpet Royale at your next BBQ.
