Blend the ingredients: Add the cantaloupe, banana, ice cubes, juice, greek yogurt, sweetener, vanilla extract (optional), and salt to a blender. Cover the blender and run the machine on medium to high speed until all of the ingredients are blended smooth. This should take roughly 3 minutes.
Adjust the thickness of the smoothie (optional): At this point the smoothie is technically done, and if the consistency is how you like it then skip this step. But if you’d prefer it to be a bit thicker/thinner then you can easily adjust it depending on your preference. To make the smoothie thinner simply add in little more juice and blend everything for another 15 to 30 seconds. If you want to make the smoothie thicker then you can add more frozen fruit or ice and blend it all together until smooth.
Adjust the sweetness of the smoothie (optional): Once the smoothie is the right consistency then you should taste the smoothie for sweetness. If it is sweet enough for you then don’t do anything. However, if you’d like it to be sweeter then simply add a little bit more sweetener and run the blender for a few seconds to incorporate it into the drink. Just make sure to add roughly a teaspoon at a time and taste as you go until it is how you like.
Pour the banana cantaloupe smoothie into glasses and enjoy immediately!
