1. Pour dressing over steaks in resealable plastic bag; seal bag. Turn bag over several times to evenly coat steaks with dressing. Refrigerate 30 min. to marinate.
2. Preheat grill to medium-high heat. Remove steaks from marinade; discard bag and marinade.
3. Grill steaks 4 to 5 min. on each side or until medium doneness (160°F.) Brush steaks with steak sauce; let stand 10 min. Cut into thin slices to serve. Garnish with grilled cherry tomatoes, if desired.
