For Seoul-born restaurateur Chung Jae Lee, toasted sandwiches involving cabbage offer a taste of home like nothing else.
"The main food staples that made up our meals growing up were rice, miso soup, kimchi and seaweed," says Lee. "But a few times a month, my mum, Soon, would buy white sliced bread, she would always make us gilgeori toasted sandwiches as a late afternoon snack."
Gilgeori toast is a popular sweet-and-salty egg fried sandwich sold by street vendors in Korea. But for those who grew up there, it's also a nostalgic snack, reminiscent of childhood home cooking, usually a rare treat on the occasions there was bread in the house.
Any leftover bread would become gilgeori for breakfast the next day. "She would cut [it] up in squares and serve [it] in a takeaway paper cup for me to indulge in on my way to school," he says.

It's gilgeori though that he keeps going back to when nostalgia hits.
His mum's recipe was a basic version. She put margarine in a pan and fried the bread until golden. Then she added finely chopped cabbage, a pinch of sugar and eggs. After this, she transferred the mixture to the bread and topped it with tomato sauce.

As a university student, he got it for breakfast on his way to class. In the late 80s, he combined it with flavoured milk.

The toastie's flavour was also enhanced by different cheeses and toppings like mayonnaise.
Lee says it even began to look different. "They now make the omelettes in a square shape to exactly match the [shape of the] sliced bread."
I would be so hungry that I couldn't resist the smell of the sandwich coming from the food truck vendors on the streets.
When Lee moved to Adelaide in the early 1990s, he didn't see much Korean food, so as a self-taught chef, he started a Korean street-food catering business that served gilgeori. His customers loved it. He then went on to open his first mainstay called Mapo. Currently, he is the owner of Seoul Sisters in Adelaide, which offers Korean basics with twists to suit the Australian palate.

"I guess when the girls ask for gilgeori, as a dutiful dad, I will make it, but I love it when they do, as it does bring back memories and I get to eat it too."
