Heat butter in a small nonstick skillet until melted. In a small bowl, whisk the egg with a pinch of salt. Add egg mixture to skillet.
Using a heatproof rubber spatula, gently pull the egg away from the sides of the skillet toward the center. As the eggs start to set, stir them gently until curds form, about 2 minutes.
When egg is completely set, fold the egg into quarters and place on the bottom half of the English muffin or baguette. Add cheese, bacon, sausage, or herbs, as desired; top with remaining half of English muffin or baguette.
