Clean the squid thoroughly and cut it into bite-sized pieces.
Slice the cabbage, onion, carrot, and other vegetables into bite-sized pieces.
Heat cooking oil in a pan and stir-fry the squid first.
When the squid is about halfway cooked, add the vegetables and stir-fry together.
Add seasonings such as soy sauce, gochujang (Korean chili paste), minced garlic, and sugar, then stir-fry everything.
When all ingredients are cooked through and the seasonings are well absorbed, serve on a plate.
