Favourite smoothie recipe

I have just acquired a NutriNinja and have been making smoothies for one meal a day.

Do you have a favourite smoothie recipe that you could share please?

I am working on trial and error at the moment, but have come up with some delicious mixtures. I have found that a little bit of ginger added to the mix gives it a bit of bite; and I have been adding a pot of Actimel.
