For years, I would get up insanely early and be the first in the office, with no-one around other than the cleaners. My breakfast every day would be microwave-cooked oats - but it wasn't quite as easy as the recipe from the book makes it out to be, mostly because of the milk.
Unlike water, when you heat up milk to a high temperature in the microwave, it behaves just like it does on the stove top: it wants to crawl out of the container and nicely spread itself everywhere.
So, I developed sort of a technique that consisted of short bursts of microwaving at full blast, then stopping and stirring, and back in with bowl. I repeated that a few times, but after I had the technique down, it didn't require much attention any more, it worked quite reliably.
The oats got cooked nicely, and thanks to the pectin of an apple that I also added in, it also thickened. (And in case you wonder, the apple's acidity does sometimes split the milk somewhat, but in most cases it doesn't.) However, there's definitely a difference in smoothness between microwaved oat meal and one that's made slowly on the stove top - the latter being much nicer in texture.
But it was a quick breakfast that I really enjoyed (with a dash of cinnamon) at my desk every morning while I was going through my email from the night before.
