Add the ingredients to the blender:
Begin by adding the spinach, banana, and frozen fruit to your blender.
Add the liquids:
Pour in the Greek yogurt (or almond milk) and water or ice. If you're adding honey or maple syrup, include it at this point.
Blend until smooth:
Blend on high speed for 30–60 seconds or until smooth and creamy. Add more water or ice if you prefer a thinner consistency.
Taste and adjust:
Taste your smoothie and adjust sweetness if needed. You can add more honey or syrup, or extra fruit for sweetness.
