<human>:  What is the best way to cook an omelette?
<bot>: The best way to cook an omelette is to whisk together eggs, milk, salt, and pepper in a bowl. Heat a lightly oiled skillet over medium-high heat, then pour in the egg mixture. As the eggs set, use a spatula to lift the edges and let the uncooked egg run underneath. When the eggs are cooked through and no visible liquid egg remains, top with your desired fillings and fold the omelette in half before sliding it onto a plate.
