No longer just for Mediterranean restaurants or health food junkies, Greek yogurt has gone mainstream in just a few years. According to a recent story in NPR, food industry analysts predict this year’s Greek yogurt sales will total around $1.5 billion (up from $60 million last year). Take a stroll down the dairy aisle of your supermarket and you’ll find multiple brands of the creamy white stuff – both flavored and non-flavored.
