Preheat grill to high. Cut ends off bread and save for another use. Cut bread into 16 slices and lightly brush both sides with Caesar dressing.
Grill bread for approx. 10 sec. per side or just long enough to toast and pick up grill marks. Remove from grill. Heat bacon for 10 sec. on each side, and grill Romaine hearts, cut side down, for 10 to 20 sec.
On each of eight salad plates, arrange Romaine lettuce halves, bacon, ciabatta toasts and Parmesan cheese. Top with a dollop of Caesar dressing and serve.
