First off, no, I have not tried all 500 recipes. Why review this cookbook you ask? Because I've had a blast using this one lately, and I have about 10 years of experience using recipes from Cooking Light Magazine. I hope that gives me enough legitimacy, because I really want to share my view about CL's greatness! They really know what they're doing. A lot of my favorite, go-to recipes came from CL. My only wish is that this cookbook and others provided more vegetarian/vegan recipes (very often light fare). I prefer their cookbooks over their magazines, which tend to have more variety with main dishes beyond meat-heavy ones.
