In a spacious mixing bowl, combine the rolled oats, almond milk, finely grated apple, chia seeds, ground cinnamon, maple syrup, Greek yogurt (if desired), and a pinch of salt.
Mix all the ingredients thoroughly until well combined, ensuring the oats are fully covered by the liquid for optimal absorption.
Evenly distribute the mixture into two or three jars or airtight containers for storage.
Seal the jars tightly and place them in the refrigerator overnight, or for at least 6 hours, allowing the oats to soak up the almond milk and soften beautifully.
When ready to serve in the morning, give the oats a good stir. If you prefer a creamier texture, add a splash of additional almond milk and mix well.
Finish off by topping with your choice of chopped nuts and a light dusting of extra cinnamon for an aromatic touch before serving.
Notes
For a beautiful breakfast, layer the oats in clear jars to showcase the lovely colors and textures, and add a slice of apple on top for a fresh, inviting look.
