I saw this on a website and just had to try it.
Place two or three eggs in a ziploc sandwich bag and shake them up a bit. Add a handful of diced ham, some bell pepper, salsa, shredded cheese, whatever you like. Close the bag securely and toss it into a pan of water on a low boil. Leave it there for ten minutes or so and then empty contents of bag onto a plate. Let it sit for two or three minutes and behold, you've made the world's easiest omelet, one that can be prepared at home or over a campfire.
It works. Amazing. Let everyone select their own toppings and make them all at the same time. Brilliant.
