When I want a rich delicious dessert treat while out and about, one of my favorite safe goodies is Arby's Chocolate Turnover. There is no yeast, no leavening, just light flaky puff-pastry and creamy rich chocolate. In fact, I just devoured one before remembering that I intended to take a picture of the next one I got, so I have this stock googled picture.
At just a dollar, it is a wonderful deal and so tasty!
For the record, although Arby's makes two other flavors of turnovers, this is the only one that is yeast free.
