How to Make It
Combine first 4 ingredients in a bowl; stir well. Let stand 15 minutes. Remove fruit from bowl, reserving syrup.
Thread pineapple cubes and plum wedges alternately onto 2 (6-inch) skewers. Prepare grill or broiler. Place kebabs on grill rack or broiler pan coated with cooking spray; grill or broil 4 minutes on each side or until thoroughly heated. Drizzle reserved syrup over kebabs; sprinkle with cookie crumbs. Serve with vanilla low-fat ice cream, if desired.
