2 frozen bananas: For easy preparation, run under cold water and peel away the thin outside layer of the skin. The peel is actually very nutritious, however unless your eating organic bananas, its a good idea to remove the top skin layer while keeping as much of the peel as possible.
a thin slice of ginger
Optional: 1/2 leaf of romaine lettuce (balances the sweetness and aids in digestion)
3/4 cup of water ( depends on desired thickness )
