Start by ensuring your pineapple is ripe and sweet. The sweetness of the pineapple will play off the bitterness of the kale.
Thoroughly wash and de-stem the kale leaves. You want the soft leafy part, not the hard stem.
In your blender, combine the pineapple, kale, and half of the coconut water. Start the blender on a low setting.
As the mixture blends, slowly increase the blender's speed. If the mixture is too thick, add more coconut water.
With the blender running, toss in the chia seeds. They'll provide a lovely texture and a nutritional punch.
If you like your smoothie a bit sweeter, now's the time to add that honey or agave syrup. But remember, it's optional!
Finally, toss in those ice cubes and blend until smooth.
