Heat grill, or grill pan to medium high. Pound chicken to create thin cutlets about ¼ inch thick. Season with garlic salt and pepper and grill until cooked through, 4 to 6 min. Place one cheese slice on top of each cutlet to melt.
To make each sandwich, spread one piece of toast with mayonnaise and one piece with a generous layer of pepper jelly. Fill with chicken, bacon and arugula to assemble the sandwich. Serve.
