01 - In a medium bowl or large jar, mix together the oats, milk, Greek yogurt, chia seeds, honey or maple syrup, vanilla extract, and salt. Stir thoroughly until fully incorporated and smooth.
02 - Gently fold in the diced strawberries and strawberry jam if using, ensuring even distribution throughout the mixture.
03 - Divide the oat mixture evenly between two jars or containers, leaving about half an inch of space at the top for toppings.
04 - Cover containers tightly and refrigerate for at least 6 hours, preferably overnight. The oats will soften and absorb the liquid, creating a creamy consistency.
05 - In the morning, stir the oats well and add a splash of milk if the consistency is too thick. Top with additional sliced strawberries, granola, or chopped nuts before serving.
