For me gardening is therapeutic, it's also the source of the freshest food I get to eat and it's also beautiful. To me it's more beautiful than a perennial border. The satisfaction for me is gustatory as well as aesthetic and therapeutic.
Even if your idea of being a foodie is, like me, putting together some organic veggie nachos, you'll dig how eloquently, warmly and straightforwardly Michael Pollan communicates to the masses.
