In resealable food container, mix together quick oats, yogourt, milk, walnuts and maple syrup. Top with blueberries. Chill 6 hr. or overnight.
Tips: To switch up tastes, change the yogourt flavour, choice of nuts (almonds, pecans, pistachios), type of sweetener (honey, brown sugar, agave syrup) or choice of fruit (berries, chopped kiwi, peaches, etc.)
