Make sure to use a firm-crusted bread, like Italian ciabatta or French baguette, for these sandwiches, since it can stand up to the weight of the ingredients and absorb their moisture without falling apart.  For a variation of this recipe as seen on "Mad Hungry" TV, swap out the Italian ingredients and use slices of turkey (leftovers from Thanksgiving are perfect) and cheddar cheese with a spread of cranberry relish on the bread. You can also try it with turkey, Swiss cheese, and cabbage. From the book "Mad Hungry" by Lucinda Scala Quinn (Artisan Books).
