One mug of water
A half mug of orange juice
A half mug of milk (full or skim, to taste)
A half mug of berries (strawberries or mixed)
It's very lovely.
I like it very cold, so I use chilled water and frozen berries, sometimes even frozen bananas (peel before freezing!) and a few ice cubes.
If you want it more desert-like, add more berries.
You can make it more mellow and nourishing by adding protein powder.
