Cut the chicken breast and squid into bite-size pieces.
Slice the vegetables such as onion, green onion, and carrot into easy-to-eat pieces.
Heat cooking oil in a pan and stir-fry the chicken breast first.
When the chicken breast is halfway cooked, add the squid and vegetables, and stir-fry together.
Add seasonings such as gochujang (Korean chili paste), soy sauce, minced garlic, and sugar, then continue stir-frying.
Once all ingredients are cooked and the seasoning is well absorbed, turn off the heat.
Finish by sprinkling sesame seeds and a drizzle of sesame oil.
