Pat chicken dry and season with salt, pepper, and garlic powder.
Heat oil in a skillet over medium-high heat. Add chicken and cook for 5–6 minutes per side until golden and internal temperature reaches 165°F (74°C).
Remove chicken and let rest for 3 minutes. Slice into strips.
In a bowl, whisk Kewpie sesame dressing, soy sauce, and honey. Taste and adjust sweetness/saltiness.
Toss sliced chicken in the sauce until fully coated.
Plate over rice or salad. Drizzle extra dressing, sprinkle sesame seeds, and garnish with green onions.
