Nostalgic indulgence!  This brings be back to the ice cream sundae birthday parties I attended as a child, although it's now frozen yogurt ... so that MUST be healthier right?  Grab a cup, pick your flavor(s), and then add as many toppings as you'd like.  My personal favorite flavor is the Green Apple Sorbet - a cool and tart treat that's light in the stomach but not on flavor.  It's my go-to tasty treat.
