Add 1 tablespoon oil to pan; swirl to coat. Dip chicken in egg mixture; dredge in panko. Coat panko lightly with cooking spray. Add 6 chicken cutlets to pan; cook 3 minutes on each side or until golden and done. Repeat procedure with remaining 1 tablespoon oil, remaining 6 chicken cutlets, and cooking spray.
