Place fruit in a small dish and nuke in the microwave for about 25 seconds, or until they get warm and squishy (or skip this step and just add it fresh).
Place the oats, milk, yogurt, chia seeds (or flaxseeds), and protein powder (if using) in a empty nut butter jar or tupperware. Mix well.
Place in the fridge and leave overnight. The oats will become soft as if they have been cooked. The chia seeds will “plump” up the oats and make it taste like a creamy breakfast pudding
In the morning, add your favorite toppings! I love topping mine with almond butter or peanut butter and fresh fruit!
