01 - Pat the chicken breasts dry with paper towels. Cut into bite-sized pieces, approximately 1-inch cubes. Season evenly with salt and black pepper, then toss with cornstarch until thoroughly coated on all sides.
02 - In a medium bowl, whisk together honey, soy sauce, minced garlic, rice vinegar, sriracha if using, and sesame oil until well combined. Set aside until ready to use.
03 - Heat vegetable oil in a large skillet over medium-high heat until shimmering. Add coated chicken pieces in a single layer, working in batches if necessary to avoid overcrowding. Cook for 3–4 minutes per side until golden brown and cooked through, reaching an internal temperature of 165°F.
04 - Reduce heat to medium. Pour the prepared sauce over the chicken, stirring to coat evenly. Simmer for 2–3 minutes until the sauce thickens and creates a glossy glaze. If sauce becomes too thick, add 1–2 tablespoons of water to reach desired consistency.
05 - Remove skillet from heat immediately. Sprinkle with chopped green onions and toasted sesame seeds. Serve hot over steamed jasmine rice or alongside steamed broccoli for a complete meal.
