In a medium-sized lidded glass container, combine rolled oats with fresh orange juice and a pinch of salt. Stir well to ensure the oats are fully coated. Seal the container and refrigerate overnight.

The next morning, take the container out of the fridge and add in the vegan Greek yogurt and freshly squeezed lemon juice, mixing everything together thoroughly.

Grate the Honeycrisp apple and fold it into the mixture along with the chopped walnuts, pure maple syrup, and ground cinnamon.

Spoon the overnight oats into serving bowls or jars. Top with fresh blueberries, additional walnuts, and a sprinkle of grated apple.
