In a small bowl, combine the orange juice, orange zest, soy sauce, vinegar, honey, garlic, salt. Add the cornstarch and whisk until well combined. Set aside.
In a large saute pan or stir-fry pan, heat the olive oil over medium-low heat. Add the chicken and cook for about 5 minutes or until the chicken is cooked through. Remove chicken from pan to a plate.
Add the broccoli and peppers. Scrape the browned chicken bits from the bottom of the pan and stir into the vegetables. This will add more flavor to the dish.
Add ½ cup water to pan, cover and let the vegetables steam for about 2-3 minutes.
Add the chicken and the orange mixture back to the pan. Mix together well. Bring to a boil. Cook for about 2-3 minutes or until the chicken and vegetables are cooked through.
Serve over your favorite cooked rice.
