Eggs, yogurt, oatmeal packets, and English muffins when nobody has time to cook a full plate.
Greek yogurt with granola takes one bowl and no stove. Keep fruit washed so topping does not become the delay.
Eggs and spinach cook while the coffee drips. English muffins toast in the same window for sandwiches you can wrap and go.
Oatmeal packets live in desk drawers and backpacks. They are not fancy, but they beat skipping food until noon.
