Add the chopped frozen mango (reserving a few pieces for topping), frozen banana, unsweetened almond milk, full-fat Greek yogurt, and freshly squeezed lime juice to a high-speed blender. Blend on high until the mixture is smooth and creamy. If the smoothie is too thick or isn't blending easily, add a bit more almond milk until you reach your desired consistency. I like to blend just long enough to keep the smoothie thick and frosty.

Pour the blended smoothie into glasses. Garnish each serving with the reserved diced mango and, if desired, a few fresh mint or basil leaves for a fresh aroma and flavor. Serve immediately for the best texture.
