I made this with plain Greek yogurt, 6 packets of Splenda instead of sugar, and added 1/8 tsp. of almond extract. This is the best strawberry/banana smoothie recipe I have found so far. Add more ice if you want it thicker.
Great basic smoothie. I made two changes. Used only half of the Splenda called for and used frozen whole strawberries so left out the ice. Turned out very thick without the ice watering it down. Made for the 2012 Think Pink event.
