Pulse until well combined, then blend on medium low speed until smooth.

Notes
Using fresh peaches: If using fresh peaches you may find you need to adjust the amount of liquid added. Banana: You can use fresh or frozen banana. Greek Yogurt: You can replace with regular yogurt, or dairy free yogurt if desired. For best results, add liquid to your blender first. Juice may also be used, but will add sugar to your smoothie.
