A great way to start off your day! For a creamier taste, use milk in place of orange juice. You can use vanilla yogurt instead of plain yogurt, if desired.
I too grind my oats to a fine powder in my Vitamix before adding the rest of the ingredients. Both my mango and banana were frozen and I used coconut Greek yogurt and Silk coconut milk since I did not have orange juice. It was pretty tasty. - 12 Jul 2016 (Review from Allrecipes US | Canada)
I always put the oats in first on an oatmeal smoothie, grind them to a powder (simply because I like that texture better than pieces of oatmeal), and I used vanilla Greek yogurt instead of plain. My mango was not frozen, so I did add some crushed ice to reach that perfectly chilled, creamy, thick texture. Enjoyed today as an afternoon snack. Very nice smoothie. - 05 May 2015 (Review from Allrecipes US | Canada)
I recently purchased a Vitamix blender and have been searching for smoothie recipes that my family will enjoy. This was refreshing and full of flavor. I substituted a peeled orange for the orange juice and added a half a cup of milk in order to have enough liquid. I didn't have plain yogurt so I used vanilla instead. I'll definitely make this again, great recipe. - 20 Jan 2017 (Review from Allrecipes US | Canada)
