01 - In a medium mixing bowl, combine the rolled oats, milk, Greek yogurt, chia seeds, maple syrup or honey, vanilla extract, and a pinch of salt. Stir until all ingredients are thoroughly incorporated.
02 - Add the blueberries, lemon zest, and lemon juice to the bowl. Fold gently to distribute the fruit and citrus flavors evenly without crushing the berries.
03 - Divide the mixture evenly between two jars or airtight containers with lids.
04 - Seal the containers and refrigerate for at least 8 hours or overnight, allowing the oats to soften and the flavors to meld together.
05 - In the morning, stir the oats well. Add a splash of milk if a thinner consistency is preferred.
06 - Top with chopped nuts, extra blueberries, and a sprinkle of additional lemon zest before serving, if desired.
