I've been cutting calories and the best substitute for wine I've found is a glass of Calistoga with Lemon Zest Ice. It's pretty easy to do. Basically, you zest lemon or limes or both together and place a little bit in an ice cube tray and fill with water and freeze. The result are cubes of zesty citrus. Take four cubes and put into a glass and fill with your favorite sparkling water!
