Overnight Oats are perfect for busy mornings. Combine 1/2 cup of rolled oats, 1 banana (sliced), and 1 cup of your choice of milk in a jar. Let it sit in the fridge overnight, and you have a ready-to-eat breakfast with around 300 calories. You could also make Banana Oat Pancakes by blending the oats into flour and mixing them with the banana and eggs for a quick pancake recipe.
