Assemble sandwiches by slicing rolls and placing on a work surface. Spread the mustard on each side of both rolls. Put a slice of cheese on the bottom of each roll. Add the pork, ham and the pickle slices. Finish with the remaining cheese and the top of the roll. Brush the top with the olive oil.
Fit the Cuisinart® Griddler® with the grill plates. Turn unit on. Select Grill and set to 375°F.
Once preheated, place the sandwiches on the grill and free the floating hinge. Press the sandwiches firmly when closing the grill and set the count-up timer. Keep it pressed for about one minute. Continue cooking for about 6 minutes total, until bread is crisp and cheese is melted.
