Pour 3/4 cup of Kraft Viva Italian Dressing over the flank steak in a shallow dish.

Cover the dish and refrigerate for at least 30 minutes to marinate.

Drain the steak and discard the marinade.

Preheat a greased grill to medium heat.

Grill the steak for 8 minutes on each side, or until cooked to your desired doneness.

Remove the steak from the grill and let it rest for a few minutes.

Cut the steak across the grain into thin strips.

Place the mixed salad greens in a large salad bowl.

Add the steak strips and halved cherry tomatoes to the bowl.

Pour the remaining 1/4 cup of Italian dressing over the salad.

Toss the salad gently to coat all ingredients with the dressing.

Sprinkle the seasoned croutons over the salad before serving.
