Add green onions and sausage to the pan.

Stir-fry until the green onions and sausage are golden brown.

Add sugar and stir-fry until it dissolves.

Pour soy sauce along the edge of the pan to create a smoky flavor.

Add chopped sour kimchi and stir-fry.

Add fine gochugaru and a little water, then continue to stir-fry.

Turn off the heat, add cold instant rice, and break it apart with a spatula or ladle.

Mix everything thoroughly, then spread the rice evenly across the pan.

Sprinkle with sesame salt and, optionally, add a few drops of sesame oil.

Plate the kimchi fried rice and top with a sunny-side-up fried egg.
