If you enjoy the fresh feeling of starting your day with an orange juice you will certainly enjoy this green smoothie. Simply mix one small orange, half a organic banana (if the fruits have been in the fridge even better), with a large handful of organic spinach and a splash of fresh orange juice. If to zesty for you, add more banana or some honey.
For a true superfood smoothie, add some spirulina too. Personally I am not the biggest fan of the taste but I add it always to the small left oven in my blender and "shot" it before serving the green smoothie.
