Drain marinated artichoke hearts and set aside, reserving marinade. In small bowl, whisk olive oil, vinegar and reserved marinade. Alternately layer basil leaves, tomatoes, cheese and artichoke hearts on platter. Rewhisk marinade and drizzle to taste over entire platter (use any remaining marinade as salad dressing). Serve immediately. Alternatively, salad can be composed on 6 small individual plates.
