Prepare grill to medium heat. In small bowl, whisk together ¼ cup oil, vinegar and 1½ tablespoons Citrus Herb Seasoning. Set aside.
Brush Romaine halves and tomato halves with remaining 2 tablespoons oil. Sprinkle with remaining 1 tablespoon Citrus Herb Seasoning. Place on grill. Grill, turning occasionally, until lettuce and tomatoes are charred, about 4-5 minutes.
Remove from grill. Cut tomatoes into wedges. Place Romaine halves on salad plates with tomato wedges. Drizzle with vinaigrette and sprinkle with cheese, if desired.
