Prepare the chicken
Place the chicken breasts between two pieces of parchment paper or plastic wrap.
Pound them to an even thickness so they cook quickly and stay juicy.
Season the chicken
Sprinkle both sides with salt, black pepper, and garlic powder.
This keeps the chicken flavorful even before the sauce goes on.
Set up the breading station
Place flour in one shallow bowl.
Add the beaten egg to a second bowl.
Add the panko breadcrumbs to a third bowl.
Bread the chicken
Coat each chicken breast in flour and shake off the excess.
Dip it into the egg, then press it into the panko until fully coated on both sides.
Fry the chicken katsu
Heat the oil in a skillet over medium heat.
Once hot, add the breaded chicken and cook for about 3 to 4 minutes per side, or until golden and cooked through.
The chicken should reach 165°F in the thickest part.
Rest and slice
Transfer the chicken to a paper towel-lined plate.
Let it rest for a couple of minutes, then slice it into strips.
Prepare the rice
Spoon the cooked rice into a bowl or bento container.
Sprinkle furikake over the top for savory flavor and texture.
Make the quick cabbage
Add the thinly sliced red cabbage to a small bowl.
Toss with rice vinegar and let it sit for 10 to 15 minutes while you finish the other components.
Cook the broccoli
Blanch the broccoli in salted boiling water for 1 to 2 minutes, just until bright green and tender-crisp.
Drain well, then toss with sesame oil and sesame seeds.
Assemble the bento
Add the furikake rice, sliced chicken katsu, broccoli, pickled cabbage, and cherry tomatoes to your bento box.
Drizzle tonkatsu sauce over the chicken or pack it separately for dipping.
