Gibbons, of Slim Gourmet repute, is certainly not the worst of the diet-cum-convenience writers. But she can hardly be called inspiring. The best recipes here are for things like blender gazpacho and salade nicoise that are hard to ruin. Most of the meat dishes have at least one obtrusive processed ingredient like catsup, or present so-so versions of classics like boeuf bourgignon in nonstick pans that prevent proper browning. Dreadful things go into most of the salad dressings--pectin, mango, or peach nectar, Bloody Mary mix--and the sauces (there is low-calorie Italian dressing in the pesto). Yogurt scrambled eggs, sauerkraut with applesauce, and a French-bread version of pizza are among the more edible offerings. Shopping stratagems, suggested diet menus. Of its kind, medium-dreary.
