Coat the Chicken: In a medium bowl, toss together the chicken, salt, pepper, and cornstarch until evenly coated. Set aside.
Make the Sauce: In a small bowl, whisk together the soy sauce, honey, sriracha, garlic, ginger, rice vinegar, and red pepper flakes.
Sear the Chicken: Heat a large cast iron or stainless steel skillet over medium-high heat. Once hot, add the olive oil and swirl to coat the bottom. Add the chicken in a single layer and cook undisturbed for 4–5 minutes until golden brown and crispy on one side.
Cook the Chicken Through: Turn the heat down to medium. Flip the chicken pieces and cook for another 1–2 minutes, stirring occasionally, to brown on all sides.
Add the Sauce: Pour the sauce mixture over the chicken and cook for 3–5 minutes, stirring frequently. The sauce will bubble, thicken, and coat the chicken in a sticky glaze.
Garnish & Serve: Remove from heat and sprinkle with toasted sesame seeds and chopped green onions. Serve warm over rice, noodles, or steamed vegetables.
