Combine the oats, chia seeds, cinnamon, nutmeg and salt in a medium bowl or container with lid. Stir in the almond milk, vanilla (if needed) and maple syrup until well combined. Stir in the walnuts.
Cover bowl with plastic wrap or place lid on container. Refrigerate overnight.
Stir in the chocolate chips before serving in the morning. Enjoy!
Notes
* I grind my chia seeds in my coffee grinder. Grind small amounts at a time and keep refrigerated for maximum freshness.
