In a medium bowl, combine the rolled oats, almond milk, Greek yogurt, shredded coconut, vanilla extract, and a pinch of salt. Stir well to combine all the ingredients.
Gently fold in the fresh blueberries, reserving a few for topping later.
If you prefer a sweeter taste, add honey or maple syrup, stirring until fully incorporated.
Divide the mixture evenly into two jars or airtight containers, covering them with lids.
Refrigerate the jars overnight (or for at least 4 hours) to allow the oats to soak and soften.
In the morning, stir the oats to combine, and add a splash of milk if you prefer a thinner consistency.
Top the oats with additional fresh blueberries, a sprinkle of shredded coconut, and chopped nuts or seeds if desired.
