If you want to fuel up in the morning (or any time of day), oatmeal is a great way to do it. It's high in whole-grain fiber and protein and low in calories. If you stay away from the flavored instant packets, it's also sugar-free and in all oatmeal's forms — whole oat groats, steel cut, Scottish and rolled — the nutrition remains basically the same.

Oatmeal is a type of porridge, and the two terms are often used interchangeably, but not all porridge is made from oats. A porridge is a hot cereal that can be made from a variety of grains, vegetables or even some legumes. (Remember the nursery rhyme "Peas porridge hot?"). It's most commonly boiled in water or milk until it's a mushy substance.

The list of varieties of porridge is very long. Porridge can be made from corn, for example. Many Americans eat corn-based porridges including polenta, cornmeal mush and grits, but many countries also have their own version of corn porridge. Champurrado is a Mexican porridge made from corn, sugar, milk and chocolate. In East Africa, corn flour and sorghum are mixed with other ground grains to make uji.

Porridge can also be made from potatoes, wheat, rice (rice porridge is often called congee), buckwheat, quinoa, millet, farro, sorghum, rye and spelt, as well as other grains and legumes. The basics of porridge seem to be the same all over the world — a dry grain, legume or vegetable turned into a mushy dish using a hot liquid. From there the possibilities are endless because of what can be added to the porridge.

Jamie Oliver shows how to make a big pot of plain oat porridge, and then has suggestions to serve it five different ways, including adding chocolate to it.

Adding chocolate to oatmeal might be a bit unfamiliar to many of us, but if you really want to go with the unusual, this Millet Porridge with Lavender Strawberries and Super Seeds will definitely take you out of your hot breakfast cereal comfort zone.
