Spicy Garlic-Chicken Pizza

12 ounces skinless, boneless chicken breast halves

1/2 cup sliced green onion

2 cloves garlic, minced

2 tablespoons rice vinegar or white wine vinegar

2 tablespoons reduced-sodium soy sauce

1 tablespoon olive oil or cooking oil

1/2 teaspoon crushed red pepper or 1/4 teaspoon ground red pepper

1/4 teaspoon black pepper

1 tablespoon olive oil or cooking oil

1 tablespoon cornstarch

1 16-ounce (12-inch) Italian bread shell (Boboli)

1/2 cup shredded Monterey Jack cheese

2 tablespoons pine nuts or sliced almonds

1/2 cup shredded mozzarella cheese

Cut chicken into 1/2-inch pieces. In a large bowl combine half of the green onion, the minced garlic, rice or white wine vinegar, soy sauce, the 1 tablespoon oil, the crushed or ground red pepper, and the black pepper. Add the chicken pieces; stir to coat. Cover and let stand 30 minutes at room temperature or for 1 hour in refrigerator. Drain, reserving marinade.

Heat remaining oil in a large skillet; add chicken pieces. Cook and stir about 3 minutes or until no longer pink. Stir cornstarch into reserved marinade. Add to skillet. Cook and stir until thickened and bubbly. Spoon evenly atop bread shell. Sprinkle with Monterey Jack and mozzarella cheeses.
