01 - In a mixing bowl, combine chicken pieces with cornstarch, salt, and pepper, ensuring all pieces are evenly coated.
02 - Heat vegetable oil in a large skillet or wok over medium-high heat. Add coated chicken and cook, stirring occasionally, until golden brown and fully cooked, about 6 to 8 minutes. Transfer chicken to a plate and set aside.
03 - In the same skillet, combine orange juice, soy sauce, honey, rice vinegar, grated ginger, and minced garlic. Bring the mixture to a simmer over medium heat.
04 - Stir together cornstarch and water to form a slurry. Whisk the slurry into the simmering sauce and cook, stirring constantly, until the glaze thickens and becomes glossy, about 2 to 3 minutes.
05 - Return the cooked chicken to the skillet and toss to coat thoroughly in the orange glaze. Remove from heat once evenly coated.
06 - Evenly divide cooked rice among four serving bowls. Top each portion with orange glazed chicken, steamed broccoli, shredded carrots, and sliced red bell pepper.
07 - Finish each bowl with sliced green onions and, if desired, a sprinkle of toasted sesame seeds. Serve immediately.
