In a large mixing bowl combine the cabbage, green onions, carrot and salt. Add the eggs and mix to combine.
Melt 1 tablespoon of the butter in a small nonstick skillet over low heat. Once melted add the cabbage mixture. Cook on low until the bottom is set and you are able to flip it, about 5 minutes. Flip and cook the other side until the egg is completely set, about 2 minutes. Remove the cabbage pancake from the pan and set aside.
Place the ham or Spam in a medium nonstick skillet over high heat and cook until crisp on both sides, 3 to 4 minutes. Remove from the pan and set aside. To the same pan add the remaining 1 tablespoon butter and melt over medium heat. Once melted, toast your bread until golden brown on both sides, 1 to 2 minutes per side.
Now it's time to build the sandwiches! Cut the cabbage pancake in half and place each half on a slice of toasted bread. Sprinkle each with 1 teaspoon of sugar. Add a slice of ham on top. Drizzle the remaining 2 slices of bread with ketchup, Kewpie mayonnaise and sriracha and place them on top of the ham to make 2 sandwiches. Enjoy!
