One of my favorite breakfast foods is steel cut oatmeal. I think many individuals who subscribe to a plant-based diet would agree that it is a great way to kickstart the day given that it calorie dense (so...filling), provides a good deal of carbohydrate energy, and a good deal of fiber too to keep you regular. Of course, all this sounds kind of bland, until you remember that oatmeal actually tastes good, too.
My favorite aspect of oatmeal is how simple it can be to make adjustments so that it tastes radically different each time. While some companies sell artificially flavored oatmeal, often in "instant packets," you can have the same success with organic and natural plant-based diet friendly ingredients.
