Almost twenty years ago, some of the most revered chefs in the world—including John Ash, Rick Bayless, Susan Feniger, Nobu Matsuhita, Nora Pouillon, Michael Romano, and Alice Waters—looked at the way Americans were eating and decided that they had to help change it. They had watched while processed foods replaced fresh food in our supermarkets. They saw family farms disappear and huge agribusiness corporation take over. They worried about obesity in children and adults and the associated illnesses. And they realized that Americans were losing the joy of cooking and eating fresh food.             In 1993, these visionary chefs founded Chefs Collaborative and vowed to use their influential restaurants to educate the public about a better way to nourish ourselves, a way that would be better for the planet, for our health, and for our communities.
