Clean and prepare the anchovies and Spanish mackerel thoroughly.
Cut the kimchi into bite-sized pieces.
Heat oil in a pan and stir-fry the anchovies first.
When the anchovies are golden, add the Spanish mackerel and grill together.
Once the mackerel is cooked, add the kimchi and stir-fry together.
Season with soy sauce and chili powder.
Mix everything well and serve on a plate.
