My friend Aura is a very good cook. She lives in Florida with her husband, Leo, and two adorable (I do not use that word glibly) children. When I think of Aura's cooking, I think of fruit salads, smoothies, and the freshest dishes from her native Guatemala — light, healthy, and driven by Florida's tropical fruits and vegetables. So I was surprised, one winter evening a few years ago, to sit down at her table and find a big, bubbling casserole of chicken wrapped in bacon. "It's Leo's favorite," she said, with a grin.
