Take a few of those frozen chicken breasts you've prepared before hand, and toss them in a bag with the following marinade.
1/2 cup thawed orange juice concentrate
1/4 cup honey
1/4 cup soy sauce
1 teaspoon Chinese five-spice powder
1/2 teaspoon garlic powder
4 boneless skinless chicken breast halves
In a small bowl, combine the first five ingredients. Pour 1/2 cup marinade into a large resealable plastic bag; add chicken. Seal bag and turn to coat; refrigerate for 2 hours. Cover and refrigerate remaining marinade.
Drain and discard marinade. Moisten a paper towel with cooking oil; using long-handled tongs, lightly coat the grill rack. Grill chicken, covered, over medium heat or broil 4 in. from the grill for 5-7 minutes on each side or until a thermometer reads 170°, basting frequently with reserved marinade.
