Whisk the soy sauce, honey, vinegar, sriracha, garlic, ginger, and sesame oil in a bowl. Set aside.
Cut chicken into bite sized pieces, and toss with cornstarch, salt, and pepper until evenly coated.
Heat the oil in a large skillet over medium-high heat. Add the chicken in a single layer and cook 6 to 7 minutes, turning once, until deeply golden and cooked through.
Pour the sauce over the chicken and bring to a bubble.
Serve over rice with broccoli or cucumbers, then top with sesame seeds and green onions.
