A simple overnight oats recipe can be made using rolled oats, almond milk, and sliced bananas. Just combine 1/2 cup of oats with 1 cup of almond milk and 1 banana in a jar, and let it sit overnight in the fridge. This meal is packed with fiber and can be around 300 calories. You can also cook oatmeal with almond milk, then top it with banana slices for a warm breakfast option; this version is just as wholesome, clocking in at about 350 calories.
