I picked up some Got Kosher? Spicy Tahini at Whole Foods and it's actually rather tasty (and quite spicy, although perhaps a tad oversalted). I find most of the prepared food carried at Whole Foods to be noxious, but this is an exception.
I have tried some of the other Got Kosher? offerings at Whole Foods (salads, chicken kabobs) and they are also not bad. I'm not saying they are the greatest thing out there, but they are good compared to some of the other offerings at Whole Foods.
