Yoghurt Cooler

Place all ingredients in the blender jar - cover and whiz on medium speed until well blended.
Pour in one tall, 2 medium or 3 small glasses and drink up.
Note: Use lots of ice in this one - great on hot days! To add ice: Remove the center of the cover while the blender is on - drop 3 or 4 ice cubs and blend until they're completely crushed.
