To broil chicken, place on broiler pan; broil 4 to 6 inches from heat using times above as a guide, turning once. Place focaccia on broiler pan, cut sides up, during last 3 to 4 minutes of cooking time.
If your focaccia measures less than 10 inches across, use less chicken and salad filling so the sandwiches remain easy to eat.
To reduce the fat in each sandwich by about 5 grams, substitute light Caesar salad dressing for regular dressing.
To save the time of washing and trimming the romaine, purchase romaine salad mixture or washed romaine hearts from the produce section of the grocery store.
To easily cut and handle the focaccia wedges, evenly space six 6-inch skewers around the loaf, two inches from the edge. Cut between the skewers, then arrange the wedges on a platter or on plates. Remove the skewers before serving the wedges.
