Add oats, milk, banana, blueberries, chia seeds into a blender and blend until smooth.
Pour into a jar with a lid and place in the fridge overnight. If in a rush, leave in the fridge for 2 hours.
When you're ready to eat, give the mixture a stir, top with favorite toppings and dive in. I did more frozen wild blueberries, hemp seeds and a dolip of PB Fit powder.
