Start by washing the spinach thoroughly to remove any dirt or grit.
Peel and chop the cucumber, and set it aside.
In a blender, combine the spinach, cucumber, pineapple chunks, banana, coconut water, chia seeds, and the juice of the lime.
Blend on high speed until all the ingredients are smooth and well combined.
If you prefer a colder smoothie, add a few ice cubes and blend again.
Taste and adjust sweetness if necessary (you can add a little honey or agave syrup if desired).
Pour the smoothie into glasses and serve immediately for the freshest taste.
You can customize it by adding other ingredients such as mint leaves or a scoop of protein powder for an extra nutritional boost.
For a dairy-free version, ensure you use non-dairy yogurt if you decide to incorporate it into the recipe.
