Wash the apple, Cut the apple from the core and cut into small chunks. Add apple to the blender.
Add the rest of the ingredients to the blender in the order listed.
Blend on high at least 1 minute until smooth.
If you don't have a high speed blender, combine the spinach, cauliflower rice and water together first to ensure there are no large chunks of veggies in your smoothie. Next add the nuts and blend again to get them as broken down as possible before adding the rest of the ingredients and blending again.
Add ice to make the smoothie cold! Because most of the ingredients in this smoothie are stored on the counter, I like to add ice as I like my smoothies to be very cold. Adding ice can also help reduce the amount of froth produced in the blender.
If you are using a bullet style blender, use the largest cup you have or blend the spinach with the water before adding the rest of the ingredients are combined to ensure you have enough room in your blender. I layer the ingredients in the largest cup so the weight of the apples helps to push the spinach leaves down into the liquid as it's blending.
To make the smoothie less sweet, only use 1/2 of the apple. To make the smoothie sweeter, add more banana.
