Start by preparing the ingredients.
Wash and dice the cucumber and honeydew melon.
If you prefer a colder smoothie, you can freeze the diced melon ahead of time.
In a blender, combine the diced cucumber, diced honeydew melon, Greek yogurt, coconut water, honey, lime juice, and a handful of fresh mint leaves
Blend on high speed until the mixture is smooth and creamy.
If the smoothie is too thick, you can add more coconut water or plain water to achieve your desired consistency.
Taste the smoothie and adjust the sweetness by adding more honey if needed.
Blend again to incorporate.
Once the smoothie reaches your desired consistency and taste, add a few ice cubes to the blender and blend again until the ice is crushed and the smoothie is chilled.
Pour the smoothie into glasses and garnish with additional mint leaves if desired.
