A popular item sold by Korean street food vendors, these egg sandwiches, called gilgeori toast, are easy to make at home. It is not that different from an American egg sandwich, but the addition of cabbage and a sweet dusting of brown sugar offers a tasty Korean twist that makes this recipe stand out. Cabbage, carrots, and onion are whisked together with the eggs and cooked omelet-style; the egg is topped with a generous amount of tomato ketchup and a sprinkling of brown sugar and sandwiched between two pieces of white bread that have been toasted in butter.
