1 (32oz.) carton Non-Fat Yogurt (I used Dannon Light&Fit Vanilla)
Mix sugar into yogurt until dissolved. Freeze according to manufacturer's instructions.
*Next time I will use Plain Non-fat yogurt and less sugar or entirely Splenda to cut down on points. I figured 3 WW points per 1/2c. serving for this recipe. If you use entirely Splenda you can have a whole 1c. serving for only 2 WW points.
