01 - Toss chicken pieces with 2 tablespoons cornstarch, salt, and pepper until evenly coated on all sides.
02 - Heat 1 tablespoon vegetable oil in a large skillet or wok over medium-high heat. Add coated chicken and cook, stirring occasionally, until golden brown and cooked through, about 6 to 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, stirring to combine.
04 - Mix 1 teaspoon cornstarch with 2 teaspoons water to create a slurry. Whisk into the simmering sauce and continue cooking until thickened and glossy, about 2 to 3 minutes.
05 - Return cooked chicken to the pan and toss gently to coat evenly with the orange glaze. Remove from heat.
06 - Divide cooked rice among 4 serving bowls. Top each bowl with glazed chicken, steamed broccoli, shredded carrots, and red bell pepper slices.
07 - Sprinkle sliced green onions and toasted sesame seeds over each bowl. Serve immediately while warm.
