Strawberry-Orange Smoothie

In my quest to use up stuff from the kitchen, I have rediscovered the joy of smoothies! :)
Part of this was cleaning up my cookbook shelf and finding a smoothie book I forgot we had!

This one was fantastic!

Makes 1 1/2 high-ball sized smoothies
(no idea how else to measure that! I'd say it was enough for 2)

Ingredients:
1 cup non-fat or low-fat vanilla yogurt (you could use soy vanilla yogurt to make this vegan)
1 ripe banana
1 cup frozen strawberries
4 oz. frozen orange juice concentrate

Method:
Stick all that in a blender. Blend until smooth. Pour into glasses. Enjoy.

I'm dying to try this with some frozen raspberries or blueberries in place of the strawberries. Or, how good does a triple berry smoothie sound? Yum! :)
Ooh, and how about adding something fun like a splash of rum, vodka, gin, or tequila? ;) Hey, I'm on summer break, I can play! ;)
