What Is Oatmeal?

Oatmeal is one of those “default” foods people come back to when they want predictable nutrition and a meal that fits their calorie target.

It works well as a base for balanced meals, because you can pair it with vegetables for volume, a protein source for satiety, and a sauce or seasoning for enjoyment.
