Pat the chicken dry and season with a pinch of salt and pepper. This helps the surface brown nicely, which is where the flavor party starts.
Heat oil in a skillet over medium-high heat. Add the chicken and cook until well browned and cooked through, about 6–8 minutes. Don’t rush the sear—crisp = flavor.
In a small bowl, whisk together soy sauce, honey, vinegar, garlic, and ginger. Pour the mixture into the pan with the chicken.
Let the sauce simmer for 2–3 minutes, then taste. If you want a thicker glaze, stir in the cornstarch slurry and simmer another minute until glossy.
Remove from heat. If you’re fancy, sprinkle with sesame seeds and green onions. Serve over rice or with steamed veggies.
