My kids love this idea, we use it all the time even at home:

[li]buy extra strength freezer sandwich size ziploc bags[/li]
[li]boil water with salt in a large pot
in each bag we use[/li]
[li]1 tbsp margarine or butter[/li]
[li]2-3 eggs[/li]
[li]1/4 cup ham chopped up[/li]
[li]onions, peppers, cheese....whatever you might like in an omelet[/li]

Smear margarine inside of bag
Add ingredients into bag
Seal bag
Shake and "smoosh" bag to mix your omelet
We mark the top of our bags with permanent marker
Drop the bags carefully into boiling water and wait about 7-8 minutes
It does not take long and you can tell if eggs are cooked by color and if cheese has melted, you can always Use tongs to take bag out to check if done and reseal and cook longer.
Simply open bag and eat out of bag or drop omelet on a plate
TADAAAA !!!!! easy clean up and delicious.

I alos throw some seasoned pepper and/or some salsa and maybe a little more seasoned salt then seal it back up.
