Fiber One® is too delicious to save just for breakfast.
In a medium bowl, sprinkle apple with cinnamon, and toss to coat.
In a parfait glass (or any mid-sized glass), layer half of the cinnamon-coated chopped apple, followed by half of the cereal.
Top with all of the yogurt. Continue layering with remaining apple and cereal.
Finish with whipped topping, and dig in!
