Creating Japanese Katsu Bowls can be straightforward if you follow these simple steps:

1. Prepare the Chicken: If using chicken breasts, slice them in half horizontally to create thinner cutlets. Season both sides with salt and pepper.
2. Set Up Breading Station: In three separate shallow dishes, place the flour, beaten eggs, and panko breadcrumbs.
3. Bread the Chicken: Dredge each chicken cutlet in flour, shaking off excess. Dip into the beaten eggs, allowing excess to drip off, and then coat with panko breadcrumbs, pressing gently to adhere.
4. Heat Oil: In a large frying pan, heat vegetable oil over medium-high heat until shimmering.
5. Fry the Chicken: Carefully add the breaded chicken cutlets to the pan. Cook for 4-5 minutes on each side or until golden brown and cooked through. Transfer to a paper towel-lined plate to drain any excess oil.
6. Slice the Chicken: Once the chicken is cool enough to handle, slice it into strips.
7. Prepare the Rice: While the chicken is frying, cook rice according to package instructions if not already prepared.
8. Assemble the Bowls: In a bowl, place a serving of rice at the bottom. Arrange slices of katsu on top.
9. Add Garnishes: Top with shredded cabbage, drizzle with tonkatsu sauce, and garnish with chopped green onions.
10. Serve: Optionally, add pickled ginger on the side for an extra zing.
