Mushrooms and their health-promoting benefits are the focus of this episode taking us on a journey through Greek forests, to an Athenian restaurant whose chef is a master with mushrooms and onto a conversation with the renowned Dr. Andrew Weil, whose research on mushrooms and longevity is groundbreaking. Back in her kitchen, Diane creates an easy mushroom gyro and a delicious braised mushroom and chickpea dish, and samples the wonders of a rare mushroom recipe cooked up by Chef Gikas Xenakis.
