Oatmeal is the perfect food for breakfast any time of year. Fiber-rich, and filling, a bowl of oatmeal can be topped with fresh or dried fruits, or some chopped nuts for daily variety. Try Starbucks Perfect Oatmeal, with some fruit and nut toppings, for a tasty breakfast of around 300 calories. You can also find single packages of oatmeal in most convenience stores and airports. All you need is a large cup of hot water!
