Place chicken breasts in a large plastic bag. Cover with teriyaki marinade and refrigerate for at least 2 hours.
In a small bowl, whisk together the mustard, honey, sugar, oil, vinegar, and lime juice. Refrigerate until ready to use.
Preheat grill to high and spray grill grates with nonstick cooking spray.
Place chicken breasts on grill and discard marinade. Grill, covered, for 6-8 minutes per side, or until juices run clear.
When cool enough to handle, cut chicken breasts into bite-sized pieces.
Divide romaine onto two plates. Add chicken, pineapple chunks, green onions, bell pepper, and craisins. Drizzle each with Honey Dijon mustard and top with tortilla chips. Enjoy!
