When you think of the domesticity of the various Desperate Housewives, Gaby is hardly the first one that comes to mind. But the actress who plays her, Eva Longoria, has  come out with a cookbook called Eva’s Kitchen: Cooking with Love for Family & Friends. The Texas native will actually be back in her home state on Sunday, signing copies of the book at the NorthPark Center location of Williams-Sonoma. The event begins at 11 a.m. — just in time to get it, meet Longoria and get back home to make dinner.
