01 - In a medium mixing bowl, whisk together the rolled oats, milk, Greek yogurt, chia seeds, maple syrup, vanilla extract, and salt until evenly incorporated.
02 - Gently fold in the blueberries, lemon zest, and lemon juice, stirring just enough to distribute the fruit and citrus flavor throughout the mixture.
03 - Divide the mixture evenly between two jars or airtight containers with lids.
04 - Seal the containers and refrigerate for at least 8 hours, allowing the oats to absorb the liquid and the flavors to meld.
05 - In the morning, stir the oats well. Add a splash of milk if a thinner consistency is preferred. Top with chopped nuts, extra blueberries, and additional lemon zest before serving.
