Vegetarianism is one step. Veganism, which takes dairy products, honey and eggs out of the picture, is another step. And raw food dining, or eating only uncooked foods, is yet another. Christa Emrick is a chef offering raw food preparation classes in San Antonio. These classes teach students to prepare their own gourmet raw vegetarian foods. If raw dining is too extreme for your tastes, start with dessert. «Desserts and smoothies are the gateway drugs to raw foods,» said author and raw-food expert Kevin Gianni. Emrick’s dessert class includes preparing raw pie crusts, brownies, truffles and chocolate mousse.
