Recipe from October 2010 Vegetarian Times. It says that the author, Matthew G. Kadey, RD, prefers sour to sweet and this recipe proves it. I did add a little extra Splenda, oil and a squeeze of fresh lemon juice, but I leave that up to you! I did not serve mine over spinach, rather just in a small bowl as a meal starter. Lastly, I added some pepitas (pumpkin seeds without the shell), but again the addition of nuts is your choice.
