A new installment after a long break!
I'm not sure if this really counts as a "food," but it's really good--at least if you like regular Hawaiian Punch. In fact, I don't think I've ever tasted a diet drink that tastes more like the original, and it's only ten calories per serving.
Even more good news: it's really cheap--in my experience, $2.50 for a gallon.
The bad news: it's really hard to find. Locally, in the D.C. area, I've only seen it at Wegman's, and since Wegman's is not convenient for me, I have to buy four or five at a time. Out-of-town, I've seen it in Walmart supercenters.
