Grape Spinach Smoothie

This kid ate a 1/2 cup of spinach today, and so can you. Here's the recipe
* 1 cup seedless green grapes
* 1 cup packed spinach
* 1/2 cup ice (4 cubes)
* 1/4 cup coconut milk (find in a can in the asian section)

I decided to freeze the grapes, which made the 1/4 cup of milk not enough liquid, so I added about 1/4 cup of apple juice also.
