In a high-speed blender, blend all of the smoothie ingredients together until completely smooth, about 1 minute.
Pour smoothie into one large jar or two glasses and serve.
Or if desired, pour into two large bowls. Top each bowl with half of the sliced banana, fresh fruit, granola, and seeds, as desired.
Notes
* I buy and freeze a bunch of bananas at once. That way, they’re always available when I want to make nice cream or a smoothie. On a cutting board, peel and slice and place in a freezer bag or container. Freeze until ready to use, up to 3 months.
