Crack the eggs into a mixing bowl.
Add pepper and salt to the eggs. Whisk to mix well.
Add 15 ml of cooking oil into the eggs, followed by chopped spring onions and red chilli. Whisk again until well-combined.
Add cooking oil to a non-stick pan, and heat it up over medium heat.
Add the whisked egg mixture. Immediately stir the egg gently to create a fluffy texture. When it is about 40% to 50% cooked, stop stirring and gently push the egg residue on the sides of the pan to the edges. Let it cook for about 1-1.5 minutes, for the edges to solidify and the bottom to turn brown.
When the omelette has expanded a little, and the bottom is slightly browned, use 2 spatulas and carefully and firmly flip the egg.
Let it cook for another minute, or until slightly browned on the bottom too.
Switch off the heat and gently transfer to the serving plate. Alternatively, transfer to another plate, and place the serving plate on top of it. Then, flip the omelette.
Just before serving, sprinkle some chopped spring onions and red chilli as garnishing. Serve.
