01 - Pat the chicken breasts dry with paper towels. Cut into bite-sized pieces approximately 1 inch. Season evenly with salt and black pepper. Toss chicken pieces with cornstarch until thoroughly coated on all sides.
02 - In a medium mixing bowl, whisk together honey, soy sauce, minced garlic, rice vinegar, sriracha if using, and sesame oil. Whisk vigorously until honey is fully dissolved and mixture is smooth. Set aside.
03 - Heat vegetable oil in a large skillet or sauté pan over medium-high heat until shimmering. Arrange chicken pieces in a single layer without overcrowding. Cook for 3 to 4 minutes per side until golden brown and cooked through, registering 165°F on a meat thermometer. Work in batches if necessary.
04 - Reduce heat to medium. Pour the prepared sauce over the chicken, stirring constantly to coat each piece evenly. Simmer for 2 to 3 minutes until sauce thickens to a glossy glaze consistency. If sauce becomes too thick, add 1 to 2 tablespoons water to achieve desired consistency.
05 - Remove skillet from heat immediately. Sprinkle chopped green onions and toasted sesame seeds evenly over the glazed chicken. Transfer to a serving platter and serve immediately while hot, accompanied by steamed jasmine rice and vegetables if desired.
