To assemble your sandwich start by smearing the Italian herb oil on the inside of each baguette.
Next layer each sandwich with grilled vegetables and top with sliced mozzarella. Place back of the grill and cook until cheese has melted 2-3 minutes on each side. Weigh the sandwich down with a cast iron skillet or a brick covered in aluminum foil. You can also use a cast iron burger press.
