Depends on whether you like Chinese breakfast or western breakfast. If western style breakfast, then you can choose sandwich with milk.

Sandwiches are easy to make, just get some salad, then fry an egg and two slices of ham. Ham is not as advanced as you think, go to the supermarket outside to buy ready-made, thick kind. Cut into thin slices, don't turn off the fire after the eggs are fried, put the sliced ham directly into the pan and heat it up on both sides.

Then spread some salad, if you want to eat more nutritious, you can put two pieces of greens.

Usually five minutes is all it takes, and it's nutritious and healthy with milk.

If you want a Chinese breakfast then you can choose to cook oatmeal porridge, or in advance with a pressure cooker timed to cook a good thin rice, fried a green vegetable or with other cold dishes are very convenient.

Even you can use a crockpot to bring to the company to cook. Many young people now use the crockpot to cook porridge, directly put the oats in the company, stewed with some milk and honey, the flavor is very good.
