I got this recipe from a friend after he brought some to a picnic - I fell in love with it instantly. It's from the June 2002 Gourmet magazine, but I've tweaked it to my own tastes (it can be found in it's original form in recipe # 129270). I only use Greek yogurt but plain non-fat yogurt works. I never add mayo anymore so I left that off the ingredients list - I can't taste the difference. I'm also not a fan of sweet & savory together so I leave out the fruit. Serve this with cous cous or taboulle salad, or it goes great on lettuce, pitas, croissants, and hard rolls.
