Measure out 2 cups (300g) of frozen strawberries directly from the freezer without thawing, peel and halve the ripe banana, and measure the milk, Greek yogurt, and vanilla extract so everything is ready before blending.
Pour the milk into the blender jar first, then add the Greek yogurt, vanilla extract, and the pinch of salt directly on top of the liquid to ensure even distribution.
Drop the banana pieces into the blender followed by the frozen strawberries on top; layering frozen ingredients last helps the blades pull everything down more efficiently. Secure the lid firmly before proceeding.
Start on low speed and gradually increase to high, blending for 45 to 60 seconds until completely smooth with no visible fruit chunks. If the blender stalls, add 2 to 3 tablespoons more milk and resume blending.
Taste the smoothie and add honey one teaspoon at a time if the strawberries taste tart, blending briefly after each addition. Add more frozen strawberries for a thicker consistency or a splash of milk for a thinner one.
Pour the smoothie into two tall glasses, garnish each with fresh strawberry slices on top or on the rim, add wide straws, and serve immediately for the best texture.
