deep

Hello, I am searching for a type of foaccia deep pan type bread.  Recently, on Food Network - saw episode containing bread that was baked in large pan and appeared to be about 2 inches thick.  It was then cut into squares a out 4 or 5 inches wide and sliced in half for sandwiches.  Does any one know what type of bread this could be????  IF so, what type of recipe would you use????    Thank you!!!!
