Vodka, lemondade (or limeade) and fresh mint. The mint makes it healthy :-) Buy one of those large cans of frozen lemonade... or maybe it's a small one, I can't remember! Put it in the blender with as much vodka as you like (organic vodka of course!). Add a bunch of fresh mint and fill the blender with ice and blend until slushy.

It's really good but be careful since it doesn't taste like alcohol.
