Query: McDougall and Ornish people- great book!

After almost a year on Dean Ornish's program to reverse heart disease, I had wonderful results, but got pretty tired of the recipes. McDougall has some offerings (same health program), but this book has wonderful recipes and lots of information for those of us who need it.It must be easy for vegans and vegetarians to find their way through meat free recipes, but many of us are unfamiliar with this lifestyle and have to it abruptly by heart disease or cancer. We DON'T know the things that seem obvious to long term vegetarians.This book was a Godsend for my heart disease support group. Thank you so very much.
