Spray a 12-inch skillet with the cooking spray and heat over medium-high heat for 1 minute. Add the chicken and cook for 15 minutes or until it's well browned on both sides and cooked through. Remove the chicken to a cutting board. Cut the chicken into strips. 2 Beat the orange zest, marmalade, vinegar and black pepper in a small bowl with a fork or whisk. 3 Place the chicken, rice, green onion, grapes and pecans, if desired, into a large bowl. Add the marmalade mixture and toss to coat.
