If you aren't exactly in the mood for a heavy casserole or hearty stew tonight, Cristina Ferrare's right there with you. "Eating heavy meals when the heat outside is oppressive can make you feel even more lethargic and uncomfortable," says Oprah's friend and cookbook author. Cristina's advice is to stay away from sugary drinks and diet sodas, and try making your own flavored water instead, using slices of cucumber, lemon, fresh mint and other brighteners. Read all about her ideas for flavored water here, and also check out her recipe for a beautiful summer salad with three options for dressings--each one perfect for steamy days.
