Make the regular amount of rice you usually make for the regular amount of time,
Halfway through the cook cycle (about 10 minutes into the cooking cycle)
Put a nice layer of the veggies on top of the rice
and drizzle some sesame oil and a tiny bit of soy sauce,
When there's only 3 minutes left, you crack the egg in the middle on top of the veggies,
Replace the lid and it cooks the egg in the remaining time.
Some folks don't want to use the egg and leave it out.
