Orange Julius Smoothie!

Ingredients:

1/2 cup low-fat or skim milk
1/2 cup cold water
2 tbs sugar or sugar substitute
1 tsp vanilla extract
4-5 ice cubes
6 oz frozen orange juice concentrate (I cut a 12 oz can of frozen orange juice in half and save the other half for your next smoothie)
**add one egg white (optional-helps make it frothier!)
