Once upon a time there was the granola bar, hard and crunchy, made mainly of oats, raisins and sometimes nuts. College kid fare, you ate it while backpacking, or sometimes for lunch when you smashed it up (yourself) and stirred it into yogurt. It came in one or two flavors, nothing fancy, just our definition?at the time?of a no-frills, wholesome snack. No one over the age of 30 bought granola bars, and no one over the age of 50 even knew what they were. -Publication:?Snack Food & Wholesale Bakery
