1. Combine Dry Ingredients: In a jar or a small mixing bowl, add the rolled oats, vanilla protein powder, and chia seeds. Stir them together thoroughly with a spoon or whisk until evenly distributed. This prevents clumps of protein powder later on.

2. Add Wet Ingredients: Pour in the milk, plain Greek yogurt, and vanilla extract. If you’re using maple syrup or honey, add it now.

3. Mix Everything Well: Stir all the ingredients together vigorously. Make sure there are no dry spots of oats or protein powder clinging to the bottom or sides of the container. The mixture should look consistent and slightly thick.

4. Fold in Strawberries: Gently fold in the diced fresh strawberries. You can reserve a few slices for garnish if you like, but mixing them in now allows their flavor to meld with the oats as they chill.

5. Cover and Chill: Place a lid tightly on your jar or cover the bowl with plastic wrap. Refrigerate for at least 4 hours, but preferably overnight, to allow the oats to soften and the chia seeds to swell, creating a thick, creamy texture.

6. Serve and Enjoy: The next morning, give the oats a quick stir. If they are too thick, you can add a splash more milk to reach your desired consistency. Top with any reserved strawberries or a few extra fresh berries, and enjoy your healthy, sweet snack!
