I am a registered dietitian and love this recipe as a summer treat! Check out my website at personalrd.com to see the ingredients I used to make it even lower in added sugar!

This pomegranate float recipe, which uses low-calorie pomegranate-flavored seltzer, pomegranate juice, vanilla frozen yogurt and fresh blueberries, is a refreshing, fruity twist on a malt-shop ice cream float. Combine ingredients just before serving.
