How can I make a fluffy omelette using beaten eggs?

To make a fluffy omelette using beaten eggs, whisk the eggs vigorously until they are well combined and slightly frothy. Cook the eggs in a non-stick pan over medium heat, gently stirring and lifting the edges to allow the uncooked eggs to flow underneath. Once the eggs are mostly set but still slightly runny on top, add your desired fillings, fold the omelette in half, and serve immediately for a fluffy texture.
