An omelette is a versatile and quick recipe that can be customized with your favorite ingredients. Beat eggs in a bowl and season with salt and pepper. Heat a non-stick pan, add a little oil or butter, and pour the beaten eggs. Cook until the edges are set, then add your desired fillings such as cheese, vegetables, or cooked meats. Fold the omelette in half and cook for a few more minutes until the cheese is melted. Serve with toast or a side salad.
