Place all ingredients into the blender (see note 1 below)
Blend on high speed until the mixture is smooth.
Serve straight away.
The order you add your ingredients can make a difference to how easily your smoothie will blend. You want the liquid and easier-to-blend fruit at the bottom, nearest the blade. In some blenders, this will involve you adding them first and in others (where you have to screw on a lid with a blade and flip), you will have to add them last.
Using frozen banana gives the smoothie a lovely thick and creamy texture.
You can replace the apple, kiwi and blueberry with around 1.5 cups of chopped fruit (of choice). Fresh or frozen will work.
You can use milk of choice, dairy and dairy-free milk both work.
Chia seeds are added for extra nutrition. You can miss out or replace with flaxseed, nut butter, hemp seed, nuts or oats.
