Finely dice the red onion and make sure the sour cream is at room temperature.
In a bowl beat together the eggs, onion, sour cream, salt and pepper.
Then heat some oil in a frying pan and when hot pout in the beaten eggs.
Cook the omelet to your liking. You can either move it around to create egg curds like in the video or leave it be on a low heat before either flipping or folding the egg. All depends on your preference.
