Coconut Water with a splash of Pineapple  This is refreshing!  It's sweet, but not too sweet.  The coconut flavor isn't pronounced, and the pineapple isn't so overpowering that it tastes like syrup.  It's clean tasting.  According to the packaging, "it has five essential electrolytes, more potassium than a banana, no fat, no cholesterol, and no preservatives."  There's a smidge of fiber, 0.8 g of protein and 16 g of sugars.  I suspect most of the sugar comes from the pineapple, but "cane juice" is one of the ingredients, too. The 8.5 fl oz carton comes to 75 calories.  If you sign up for subscribe & save, it's less than $1 per carton.  Actually, the carton is the only thing I don't like about this drink.  It's sort of hard to drink directly from because there isn't any air getting let in when you drink, which makes a vacuum.  This was solved by pouring it into a glass.  *whew*  This was good.  I will definitely get more, and I highly recommend this to people who like pineapple juice.

Here's a tiny consolation: easy Thai barbecued chicken! Cut your usual fryer in quarters, cook it slowly over charcoal or quickly in a hot oven, and then brush it generously with "sweet chili sauce" and cook it just a few minutes more. Most authentic with 'sticky' rice but also delicious with brown or red rice.  In Thailand, people squat over hibachi-sized braziers on the sidewalks and sell portion of this sort of barbecued chicken. Sometimes they trot alongside inter-city buses as they pull into stations, and sell chicken through the windows. Don't be squeamish! This is a treat you'll remember. The same sauce will enhance the flavor of any fowl from blackbird to condor or whooping crane.

Makes pretty good cocoa and a lot easier than on the stovetop.  Not as sweet as I would prefer and needs to be stirred to keep it in suspension.  I guess I can add marshmallows:-)
