Cold Mango Oatmeal (Overnight Oats)

Place all ingredients (except blueberries for garnish) in a blender and mix until you get a fine and homogeneous mixture, with a consistency similar to a fluid batter. If the oatmeal seems too thin, add another tablespoon of rolled oats; if it's too thick, add a little more almond milk.

Pour the mixture into a bowl or jar and leave it in the refrigerator overnight (or at least a few hours) for the flavors to meld. Before serving, decorate with fresh blueberries, coconut flakes, chia seeds, or any other fruits you prefer.
