Prepare your ingredients: frozen watermelon, frozen strawberries, Greek yogurt, honey, water or unsweetened almond milk, and fresh mint.

Combine the ingredients in the blender, starting with the frozen watermelon and strawberries, followed by the Greek yogurt and honey, then add enough water or almond milk.

Blend until smooth, about 30-60 seconds, stopping to scrape down the sides if needed.

Taste and adjust sweetness, adding more honey if desired, and pulse briefly to incorporate.

Serve the smoothie in chilled glasses, garnishing with mint or basil.
