Works great if you're out backpacking - start the campfire in the morning, put a pot of water onto it to boil for coffee, while the water's boiling (boil a few minutes to kill any parasites in the water) toss in your omelet.
Personally, at home I wouldn't do it that way.
Add a tablespoon of bacon grease to large square pan
heat it up
while it's heating, dice up some leftover ribeye; use the leaner portion
toss that into the pan
while that's heating up, scramble 5 or 6 eggs in a bowl
remove meat from pan
pour egg into pan
cook slowly until it's nearly cooked through - slowly enough that the bottom doesn't become brown
sprinkle the meat on top of the nearly cooked egg mixture, add some shredded cheddar cheese.
fold over 1/3 from the left and from the right; let it heat for another minute, flip it, and another minute to make sure it's cooked through.
Enjoy. I also prefer to have green peppers cooked with the meat, but never seem to have them on hand.
