In a large mixing bowl, combine the oats, chia seeds, milk, Greek yogurt, maple syrup, vanilla extract, and salt. Stir thoroughly until smooth.

Gently fold in the chopped strawberries, reserving some for topping.

For a layered effect, mash half of the remaining strawberries and spoon a layer into the bottom of your jars.

Cover and refrigerate for at least 4 hours or overnight.

Stir the oats gently before serving.

Add your chosen toppings, such as strawberry jam, fresh strawberries, or granola.

Combine crushed cookies or crackers with melted butter and vanilla, then toast for 1-2 minutes.

Sprinkle the prepared crumble on top of your overnight oats just before serving.
