Mince the chicken breasts, onion, and carrot in a food processor. If you don't have a food processing machine, mince with a knife.
Add the ingredients from Step 1 and the ★ seasoning ingredients into a bowl, and mix well.
Shape into thin and slightly smaller-sized hamburger steaks than normal. Lightly grease a frying pan, and fry both sides until golden brown.
Cover with a lid, and steam-fry for about 5 minutes.
Remove the lid, swirl in the teriyaki sauce mixture, and simmer until the sauce is thickened, then done.
Story Behind this Recipe
I created this dish because I wanted to knead shio-koji (which has come back into fashion) into hamburger steaks. I also wanted to make inexpensive and healthy chicken hamburger steaks with teriyaki sauce, a favorite with kids! They turned out to be fluffy and delicious.
I made minced meat with chicken breasts, including the skin. You can also use store-bought minced chicken.
