Notes
You can adjust the consistency of this watermelon yogurt smoothie by adding more frozen banana for thickness or more orange juice for a thinner texture.Feel free to incorporate other fruits like raspberries, blueberries, or strawberries for added variety.For a more pronounced pineapple flavor, use fresh or frozen pineapple instead of canned.While this pineapple watermelon banana smoothie pairs well with frozen yogurt, you can use Greek yogurt for a dairy option or vanilla ice cream if you prefer a creamier texture and don't mind added sugars.To make this smoothie dairy-free, replace the frozen yogurt with more frozen fruits or omit it entirely. Taste the smoothie and adjust the flavors to your liking.
