01 - Pat chicken breasts dry with paper towels. Cut into uniform bite-sized pieces. Season thoroughly with salt and black pepper. Toss pieces in cornstarch until evenly coated on all sides.
02 - In a medium bowl, whisk together honey, soy sauce, minced garlic, rice vinegar, sriracha, and sesame oil until fully combined. Set sauce aside.
03 - Heat vegetable oil in a large skillet over medium-high heat until shimmering. Arrange chicken pieces in a single layer without overcrowding. Cook 3 to 4 minutes per side until golden brown and cooked through to internal temperature of 165°F.
04 - Reduce heat to medium. Pour prepared sauce over chicken, stirring constantly to coat all pieces. Simmer 2 to 3 minutes until sauce thickens and glazes the chicken. Add 1 to 2 tablespoons water if sauce reduces too much.
05 - Remove skillet from heat. Sprinkle chopped green onions and toasted sesame seeds over the top. Serve immediately over steamed jasmine rice or with steamed vegetables.
