Overnight Oats with Chia Seeds

0 Combine oats, chia seeds, flax seeds (if using), and  milk. Stir in brown sugar and a pinch of salt (don't skip the salt - I think it brings out a lot of flavor in the oats, even if you skip the sugar).
1 Store oats in the refrigerator overnight.
2 Serve oats straight out of the refrigerator (or warm them up briefly in the microwave if you'd prefer). Add toppings. Enjoy!
