Preheat a grill to medium high. Combine chicken, salt, pepper, mustard, bread crumbs, lemon juice and chives in a large bowl and form into ½ inch thick patties.
Grill the patties, flipping once, until the juices run clear or it reaches 160 degrees with a meat thermometer. Top with cheese during the last minute of cooking.
Lightly grill the cut sides of the buns and serve with sliced tomato, sliced red onion, mayo, Dijon mustard or pickles.
