When I was growing up, my mother used to make fruit smoothies every day, every summer. The smoothies were delicious, but I always felt so miserably full after just one glass. Now I know why they were so filling - it was the milk! My smoothies these days consist of only fruit and water. They are light and refreshing instead of heavy and super filling. I always slice and freeze my over ripe bananas - frozen bananas make smoother smoothies! :)
Frozen fruit makes a great "ice cream" treat too! Use one part over ripe frozen banana (sliced) and one part frozen strawberries or raspberries, throw them in the blender with a splash of soy coffee creamer and liquefy on the highest setting until the fruit becomes creamy. Add more creamer as/if needed.
