Well I grew up watching my dad who used to own a resturaunt, and the first foods I started out with was breakfast. And Well, I dont know about traditional omelettes, But I always started my egg out as though I were going to scramble it on medium heat, put it in a small egg pan, then just flip it after I saw the edges becoming solid (which meant bottom was done) then flip, check it a little less than how long it took to finish the bottom. Put my stuff, onions, cheddar cheese, ham, sausage on half of the omelette, let the cheese melt for maybe 1 and a half minutes, put half of the omelette on the plate, then fold it with the pan
So My omelettes were never round lol Mine had the stuff inside like the egg was a tortilla of sorts
It all tastes the same though really, only thing thats different is the presentation
(Which more times than not, is key) lol Id say it looks good. Might want to decorate the top with some sprinkled cheese then let it melt
