This Pear Oatmeal and Blueberry Breakfast Smoothie is the ultimate breakfast smoothie, combining pear, oats, blueberries, and milk. Think of it as a hearty bowl of oatmeal packed into an easy, mix-and-go beverage. The smoothie requires no added sugar, thanks to the sweetness of the ripe pear, and the cinnamon is a perfect complement to the other flavors. Recipe courtesy of USA Pears.
