Prep the Ingredients: Start by washing the spinach thoroughly so no grit remains. Peel and slice the banana, and measure out your pineapple chunks. Keeping everything ready makes blending quick and smooth.
Add to Blender: Place the pineapple, spinach, banana, and yogurt into your blender first. Pour in the water or coconut water to help everything move easily while blending.
Blend Until Smooth: Turn the blender on high speed and let it run for about 30 to 60 seconds. Watch the mixture turn into a bright green, creamy drink with no visible spinach bits left.
Adjust Consistency: Check the thickness after blending. Add a splash more liquid if it feels too thick, or toss in a few ice cubes if you want it colder and slightly thicker.
Taste and Sweeten: Take a quick taste and decide if you want a touch of sweetness. Add honey or maple syrup if needed, then blend again briefly to combine.
Serve Immediately: Pour the smoothie into a glass right away. The fresh flavor tastes best when enjoyed immediately while it is still cold and vibrant.
