A fruity and yummy breakfast or snack. You can use fresh or frozen blueberries here. If you use fresh, you will likely need to add ice.
Combine all ingredients (except start with about half the amount of juice and add only as necessary to to achieved desired consistency) in the canister of a blender and blend until smooth and creamy. Blueberries take awhile to break down, so you may need to blend for a couple minutes.
Serve immediately. Extra portions may be frozen in freezer-safe (plastic) glasses for up to 3 months. Allow to soften at room temp before serving.
