Open the roll and lay flat. On inside of roll spread the mustard. Lay pickle slices on one side of the roll. Layer one slice of the cheese, turkey, ham and other slice of cheese on the other side of the roll. Close and grill over low heat, panini style until sandwich is crispy and cheese is melted. Serve with coleslaw, baked beans or seasoned green beans. Quick supper idea! You can use any roll of choice. Enjoy!!!
