As she's done for the last three years, First Lady Michelle Obama is getting her hands dirty sowing seeds in the White House kitchen garden this spring. When Mrs. Obama began envisioning a garden during the 2008 presidential campaign, "it was just a pipe dream," she said. "And then it started unfolding in a way that I couldn't have imagined, where we've produced thousands of pounds of food." The garden was one of the first efforts in her "Let's Move" campaign to help kids eat healthier, exercise more and encourage food manufacturers to offer healthier options. Mrs. Obama tells the story of the garden, including how daughters Sasha and Malia helped inspire its creation, in her new book American Grown (Crown, May 2012). The book features easy garden plans and mouthwatering recipes from White House chefs. Here she shares White House Executive Chef Cristeta Comerford's recipe for one of the season's first crops.
