Adding honey or any other sugars is optional but you can skip it as fruits are already sweet.
If you are trying it for the first time and getting used to the taste, you can add sugar or honey.
You can also use non-fat, plain or flavored yogurt in this parfait in place of oats and chia seeds.
I use many different fruits in parfaits like apples, oranges, and banana. The best part is that you can go creative with and include or exclude anything according to your liking.
For a parfait with yogurt, take a tall glass, add yogurt at the bottom, add granola and fruits in layers and repeat.
