Is it a healthy breakfast? There are certainly better options with a little bit more effort. But it is far less unhealthy than it used to be.
For what it's worth, I stumbled on oatmeal with a bit of honey and berries as my go-to meal. A diabetic friend brought that up as a breakfast recommended by their dietitian, and I've seen it recommended other places as well. It takes 5 minutes to prepare in the microwave at 50% power to prevent overflowing, in which time I could have completely finished a bowl of cereal.
