The introduction to this latest Weight Watchers compilation promises ``something for everyone,'' ``variety and flexibility...to fit your unique life-style.'' Which is just another way of saying that this is one more characterless Weight Watchers mishmash of convenience, contrivance, and clichÇ. Several potato dishes, including ``creamy mashed,'' are made with instant potato flakes. Fence-sitting and substitute ingredients such as light cream cheese and margarine abound. Several high-cheese dishes, such as white pizza, give more than the recommended 30% of calories from fat. Brown rice and veal dishes coexist, to the advantage of neither, as do various ethnic accents--but few if any genuine ethnic dishes. And all this comes larded with a self-congratulatory text that gushes about ``today's'' taste and health consciousness, though scores of other cookbooks have better served that consciousness for decades. Sure, there are some perfectly decent low-fat recipes here-- but in an age when perfectly decent low-fat recipes crowd our shelves, that's not enough.
