Put rice in the rice cooker. Just when it's about done, fry up an egg.

Put the rice in a bowl, put the egg on top, and then add on some seasoning! I can vouch for the following (I haven't mixed them, but you could..):

• Furikake or crushed seaweed
• Soy sauce
• Tomato sauce
• a little bit of salt and sesame oil mixed in to the rice

To make it a little fancier:

• Spring onions
• Shredded carrots
• Sliced lettuce.

Another lazy meal: Put rice in the rice cooker (or pot), put in some raw chicken and/or a shelled egg, soy sauce, oyster sauce, sesame oil, dark soy sauce. Let it cook.

To be fancier: boil or fry some frozen corn and/or peas on the side. Mix it in when rice is done.

There you have it - three food groups covered.
