The blood oranges were more tart than regular oranges. So, I added an extra banana and some frozen pineapple as well. We all enjoyed these smoothies. If you are making this with regular orange juice, a single banana would probably be all that you need.
Blood Orange Pineapple Spinach Smoothie
1 cup orange juice, I used the juice from 4 medium size blood oranges
a large bunch of spinach, approx 4-6 ounces - if the stems are very long, trim the excess
1-2 small bananas, frozen is best
1 cup frozen pineapple tidbits
Layer ingredients into the blender in the order listed above. Puree until smooth. Enjoy!
