Simply rub the flavorings into the chicken thighs and Japanese leeks and cook in a frying pan! To make it easier, I left out the step of skewering the chicken, which means that these are really easy to make!
Cut the chicken into whatever sized pieces you like and put them into a bowl. Add the seasonings, rub in, and leave to marinate for a while.
Cut the Japanese leeks into whatever sizes you like and place in a separate bowl. Sprinkle on the salt, mix, and leave it sit for a while.
Heat a frying pan and add the vegetable oil. Add the chicken from Step 1 and the leeks from Step 2. Cover with a lid and cook.
When the chicken browns, turn over both the chicken and the leeks, cover with the lid again and cook.
Story Behind this Recipe
I usually make salted yakitori by skewering chicken pieces and cooking them on a grill. I figured that you could cook them easily on a frying pan without the skewers and gave it a try. I picked up some tricks from another user's yakitori recipe (Recipe ID: 1979988).
Seasoning the chicken makes it more likely to burn, so keep a close eye on it while cooking and adjust the heat as necessary.
