I like my oatmeal on the thicker side; if you prefer yours thinner, it can be easily thinned with a few tablespoons of water or milk at the end, before serving.
If you like, you can make a large batch of this and keep it in the refrigerator for an even easier breakfast, heated up in the microwave for a minute or so. It will keep for about a week.
The flaxseed meal can be replaced with one egg, added in the same step. The oatmeal will be slightly thinner.
