Place carrot juice, orange, spinach, and ginger in blender.
Blend on medium speed for about 30 seconds.
Add ice and finish blending.
This recipe requires carrot juice, but if you don't have a juicer, you can buy prepared carrot juice. The taste is simple, clean, and slightly earthy with the addition of spinach (I used about a cup of baby spinach, but you can add less if you want it sweeter).
