Apple Mustard Stuffed Pork Chops

4 boneless pork chops, 1-1/2 inches thick
1/2 cup chopped apple
10 RITZ Crackers, coarsely crushed (about 1/2 cup crumbs)
1/4 cup coarsely chopped PLANTERS Pecans
3 Tbsp. GREY POUPON Dijon Mustard, divided
2 Tbsp. raisins

PREHEAT grill to medium heat. Make pocket in each chop by carefully making a horizontal cut in 1 side of each chop, being careful to not cut all the way through chop to opposite side. Set aside.
MIX apple, cracker crumbs, pecans, 2 Tbsp. of the mustard and the raisins until well blended. Spoon evenly into pockets in chops. Press cut sides together to seal pockets; secure with toothpicks.
GRILL chops 30 to 35 min. or until chops are cooked through, turning over after 15 min. and brushing with the remaining 1 Tbsp. mustard.
