How do you cook an omelette in the microwave?

Probably not the best idea, that will most likely be pretty gross, but I have some recommendations.
First, if you go to your local grocery store, then there may be some muffins and etc. there. They are good snacks for students on the go as well as tasty and filling as well. It may not be gourmet but it does the job.

Second, if you get an electronic kettle you can make yourself some cream of wheat or oatmeal. While some oatmeal can be mushy some brands of oatmeal can be really good especially when you add some fruit or your own special touch to it

Third, while there are electronic kettles there are electronic cookers
for instance:http://www.amazon.com/Presto-07039-22-Inch-Electric-Griddle/dp/B0000Z6JMS/ref=sr_1_6?s=kitchen&ie=UTF8&qid=1356762910&sr=1-6

and no I'm not trying to sell you this, but it is a stove-free way to make omelettes as well as other things. Like yummy pancakes. So try investing in one of these.

I hope this helped.

Microwave Omelette

Instructions
Things You'll Need

1 egg
Salt
Milk
Additional toppings to taste
Microwavable glass cereal bowl
Margarine
Teaspoon

1. Grease the cereal bowl with margarine.
2. Crack one egg into the bowl and beat with a fork.
3. Add the milk and beat. Add only enough milk to lighten the egg color slightly. Beat until there are no patches of egg white and it is combined consistently.
4. Add a pinch of salt.
5. Add additional ingredients to taste. For instance, you might like a cheddar cheese and shredded turkey omelet or a black olive and green pepper one.
6. Place in the microwave on high for one and a half to two and a half minutes, depending on the heating capability of the microwave.
7. Remove from the microwave with hot pads. A perfectly round omelet should be in the bowl.
