1. Place steak and 1/3 cup of the dressing in a large resealable plastic bag. Seal bag; refrigerate 4 to 6 hours.
2. Coat grill rack with nonstick cooking spray. Preheat grill to medium (300°F to 350°F). Remove steak from marinade; discard marinade. Place steak, corn and bell pepper on grill.

Remove steak, corn and bell pepper from grill.

4. Slice steak across grain into thin slices, and place on a serving platter. Top with salsa, and serve.
