Add the oats, Greek yogurt, milk, chia seeds, flaxmeal, maple syrup, vanilla, and salt into a mason jar (or container with a lid). Stir to combine. Feel free to omit the chia seeds or flaxmeal if you don’t have them on hand.
Place container in the fridge for at least 2 hours, but preferably overnight.
In the morning, take the container out of the fridge, remove the lid, and give the oats a good stir.
Top with your favorite toppings and enjoy!
