01 - In a medium bowl or large jar, combine the oats, milk, Greek yogurt, chia seeds, honey or maple syrup, vanilla extract, and salt. Stir until well mixed and fully incorporated.
02 - Gently fold in the diced strawberries and strawberry jam if using extra sweetness. Distribute evenly throughout the mixture.
03 - Divide the mixture evenly between two jars or containers, leaving about half an inch of space at the top for toppings.
04 - Cover tightly and refrigerate overnight, or for at least 6 hours, until the oats have softened and absorbed the liquid, creating a creamy texture.
05 - In the morning, stir thoroughly and add a splash of milk if desired. Top with extra fresh strawberries, granola, or chopped nuts before serving.
