For an extra touch of flavor, try adding a dash of hot sauce or a sprinkle of fresh herbs like chives or parsley before serving. Feel free to substitute your favorite vegetables and cheeses to customize this omelette to your liking. Spinach, tomatoes, feta, or Monterey Jack cheese are all great options. Ensure your skillet is well-seasoned or nonstick to prevent the omelette from sticking and tearing.
