Add the oats, milk, yogurt, applesauce, maple, chia, vanilla, cinnamon, and salt to a cup (or split these equally between two cups to make two portions). Whisk up the ingredients well.
Chop the apple and pecans into smaller pieces. Add half the apple and all of the pecans to the oats and mix those in with the rest of the ingredients.
Then top the oats with the rest of the apple.
Cover the oats with a lid or foil and refrigerate them overnight.
In the morning, take out the oats, and top with more pecans, cinnamon, vegan caramel, or whatever other toppings you like!
