In a pan over medium heat, add 1 tbsp butter. Toast the bread with butter on both sides until golden brown. Set aside.
In a bowl, beat 2 eggs and season with salt and pepper. Add the cabbage, onions, carrots, scallions, perilla leaves, sausage, and mix.
In a pan, add the remaining tbsp of butter and the egg mixture over medium heat. Shape the egg mixture into a rectangle that is the approximate size of two slices of bread.
Cook for 2-3 minutes, then flip and cook for another 2-3 minutes or until golden brown.
Cut the egg mixture in half. Add a slice of cheese on one half and top it with the other half.
Place the eggs on top of one slice of toast. Layer on the sugar, ketchup, mayo, chili oil then top it off with the other slice of bread.
Cut in half and serve. Enjoy!
