There are a few recipes that are similar to this recipe but not one exactly like this (this one packs a punch in flavor). I found it in a recipe book that one of Oprah Winfrey's trainers published. I put it in my own book and because I have an embarassingly huge number of cookbooks, I can't find the authors' name. The author noted that instead of the Swiss Chard, this recipe could be made with 2 packages of frozen spinach. That's how I make it because I always have frozen spinach on hand. If you use the frozen spinach, cook it according to package instructions, let it cool, then squeeze out as much of the remaining liquid as possible...I use a thin-mesh strainer to do it. It's so simple to prepare and make - it's hard to believe it's soo low fat. Hope you enjoy!
