Blend the water, lemon juice, and greens in a blender until smooth. *If you blend everything together at once the greens don’t blend very well (unless you have a high-powered blender) and the smoothie can get chunky, blending the greens with the liquid first helps avoid that.
Gradually add the apple, celery, cucumber, pineapple, grated ginger, and chia seeds until smooth/to your desired consistency.
If you want a thicker or creamier smoothie, add a spoonful of ripe avocado or greek yogurt. If you want a thinner smoothie, slowly add more water until blended to desired consistency.
Serve! Save and refrigerate the leftover smoothie in a sealed container and enjoy at a later time!
