In a mixing bowl, crack 3 large eggs and add 2 tablespoons of milk or water. Whisk vigorously for about 1-2 minutes until frothy and pale yellow.

Place a non-stick skillet on medium heat. Add 1 tablespoon of butter to melt, swirling to coat the pan.

Pour the egg mixture into the skillet. Let it cook undisturbed for about 30 seconds.

Using a spatula, gently lift the edges of the omelet and fold towards center.

Once nearly cooked, sprinkle cheese on one half and allow to melt for 30 seconds.

Fold the omelet in half, letting it cook until the cheese is melted and the omelet is golden.

Slide the omelet onto a plate, sprinkle with chives or herbs, and serve immediately.
