100-Calorie Pumpkin Pie Smoothie: - 1/2 cup ice - 1/2 cup vanilla nonfat yogurt - 1 tsp. honey - 1/4 tsp. pumpkin pie spice - 1/4 cup pumpkin puree (add half a banana if you’d like). All of these for only 100 calories, amazing. Wasn't very into it since I would never drink a smoothie that is called Pumpkin Pie Smoothie, but this seems more than reasonable.
