I don't. I used to eat about 900 calories worth of breakfast previously (two bananas, about 200g of oats, milk, cottage cheese, all in a blender). Now I just drink a coffee and stay fasted until about 1 PM which is when I have a high-protein lunch at work with some veggies.

>Factors to optimize for: - nutrition - cost - time to buy ingredients/how long they last - time to prepare breakfast/clean it - taste

This is easy. Buy Whey protein (chocolate, vanilla or whichever taste you want. Around 7$ a pound is the price, can last for a really long time. Buy instant oatmeal, around 2$ a pound is the price. Mix protein with water or milk, add oats, enjoy a tasty breakfast with only one bowl to clean. You can adjust nutrients as per your needs/liking. Probably the best breakfast optimisation one can do.

Want a carb-free breakfast without much trouble? Crack a few eggs on a plate, put them in the microwave, come back 2 mins later.
