1. Cut the chicken cutlets into large pieces, about 10 cm in size.
2. Cook the rice.
Place the cutlets in a dish, season with salt and pepper. Let them rest for 10 minutes.
3. Slice the garlic into thin strips.
Cut the pak choi into quarters lengthwise.
4. In a wok or similar pan, sauté the garlic in a little cooking oil, then add the pak choi and sauté for 4 minutes. You can deglaze with a little water or soy sauce. Keep warm.
5. Prepare 3 bowls for breading the meat. One with flour, one with beaten eggs, and one with panko breadcrumbs.
6. Bread the cutlets by dipping them in each of the 3 ingredients.
7. In a saucepan, heat the ketchup, Worcestershire sauce, oyster sauce, soy sauce, and cane sugar. Wait for the sugar to dissolve and set aside. This is the base for the Katsu sauce.
8. In a thick-bottomed pan, heat the oil (about 50 cl) and fry the breaded chicken pieces for a few minutes. Turn them occasionally.
9. Remove them from the pan and drain them on paper towels.
10. Serve the sliced chicken on a bowl of rice with the pak choi.
Drizzle with sauce and enjoy.
