Step 1

Combine the egg, cabbage, carrots and green onion in a mixing bowl. (If you’re using bacon and onion, add them now.) Add a pinch of salt and freshly ground black pepper then mix them well.

Step 2

Preheat a pan over medium low heat. Add some cooking oil then pour in the egg mixture. Cook both sides well until the egg is fully cooked. (If the omelette is thick, it will take a while to cook inside thoroughly. So to avoid it burning, you may want to reduce the heat to low.)

Step 3

Spread the butter on both sides of each slice of bread, then cook both sides over medium low heat until golden (about 1 min each side). Remove from the heat.

Step 4

Place the toasted bread on a cutting board. Add the egg omelette. You can trim the egg omelette to better fit on the toast if you want. Sprinkle the sugar on top (optional). Then layer it with cheese and ham (optional). Squeeze out ketchup and mayonnaise (optional) across the egg/ham/cheese layer. Add some pickled cucumbers (optional). Cover it with the remaining bread. Slice in the middle and serve.
