To make a fluffy omelette without using egg whites, you can focus on incorporating air into the eggs and ensuring proper cooking techniques:

     – Separate the eggs and beat the yolks vigorously until they become frothy and pale.

     – In a separate bowl, whisk the egg whites until they form stiff peaks.

     – Gently fold the beaten egg whites into the frothy yolks, being careful not to overmix and deflate the whites.

     – Preheat a non-stick skillet over medium heat and add a small amount of butter or oil.

     – Pour the egg mixture into the skillet and cook undisturbed until the edges start to set.

     – Lift the edges with a spatula and tilt the skillet to let the uncooked eggs flow underneath.

     – Continue cooking until the omelette is mostly set but still slightly runny on top.

     – Add any desired fillings to one half of the omelette and fold the other half over.

     – Cook for an additional 30 seconds to melt the cheese and finish cooking the omelette.

     – Slide the omelette onto a plate and serve while still fluffy and hot.
