Mix mustard, lime juice and adobo seasoning. Lightly pound pork chops with a meat mallet to ½-in. thickness; spread both sides with mustard mixture. Refrigerate, covered, 3-4 hours.
Grill pork, covered, over medium heat 3 minutes. Turn pork and top with ham; grill 2 minutes longer. Top with cheese and cilantro; grill, covered, 30-60 seconds longer or until cheese is melted and a thermometer inserted in chops reads 145°. Let stand 5 minutes before serving. If desired, serve with mayonnaise, mustard and pickles.
