01 - Toss chicken pieces with 2 tablespoons cornstarch, salt, and pepper until evenly coated.
02 - Heat 1 tablespoon vegetable oil in a large skillet or wok over medium-high heat. Add chicken and cook, stirring occasionally, until golden and cooked through, approximately 6-8 minutes. Remove from skillet and set aside.
03 - In the same skillet, combine orange juice, soy sauce, honey, rice vinegar, ginger, and garlic. Bring to a simmer over medium heat.

05 - Return cooked chicken to the pan and toss to coat thoroughly in the orange glaze.
06 - Divide cooked rice among 4 serving bowls. Top each with orange glazed chicken, steamed broccoli, shredded carrots, and red bell pepper.
07 - Garnish with sliced green onions and toasted sesame seeds if desired. Serve immediately.
