I was a little skeptical when I first picked this up, though admittedly for no good reason (maybe I'm a sucker for photos or general "hipness"--this book has neither). Some of the dishes I prepared because I had the ingredients already, but I had a feeling the recipes would be underseasoned or just not exciting. But no, everything was delicious, and my husband loved it as well.
It's also good for trying to wean yourself/family from meat-heavy dinners. We really enjoyed the beef and broccoli stir-fry, for example, which is lightened up simply with a higher proportion of vegetables. So too with the meat loaf.
I refuse to do "diet" cookbooks, so my other reference for lightening up my cooking is Sally Schneider's A New Way to Cook, which I also highly recommend. That book has the style, size (700+ pages), photographs, and glamour over this one, but Lighter,Quicker, Better is far more accessible in terms of ingredients and attitude, and I haven't been disappointed once.
