Meanwhile, crack and lightly beat the eggs in a medium bowl. Add a dash of hot sauce, salt, and pepper.
Turn the heat down to medium-low and pour egg mixture over leeks. Occasionally stir the eggs with a wooden spoon so they cook slowly and evenly. Right before all the runny bits are completely cooked, break the cheese into bite sized chunks and add them to the skillet. Give the mixture one more mix.
Using an oven mitt to protect your hands, place skillet in the oven under the broiler. Broil for about 5 minutes or until the top is lightly browned and fluffy.
Allow to cool for 5 minutes so eggs can set and are easier to cut and serve.
