Combine oats, chia seeds, almond milk, greek yogurt and maple syrup in bowl. Whisk and cover. Place in the fridge overnight or for at least 4 hours. The mixture will thicken to a pudding like consistency. You will have about 2 cups.
Into 2 portable jars (mason type or similar) layer ½ cup of the oat mix, ½ c apple sauce, additional ½ c oat mix.
Top with a dollop of yogurt and garnish with a dash of cinnamon and diced apple or dried apple ring.
