Marinated Sirloin Steaks

In a blender, combine the honey, soy sauce, oil, vinegar, garlic and pepper; cover and process until blended. Pour 1/3 cup marinade into a large resealable plastic bag; add steaks and onions. Seal bag and turn to coat; refrigerate for at least 1-2 hours. Cover and refrigerate remaining marinade for basting.

Coat grill rack with cooking spray before starting the grill. Drain and discard marinade. Grill steaks, covered, over medium-hot heat for 4-5 minutes on each side or until meat reaches desired doneness (for medium-rare, a meat thermometer should read 145°; medium, 160°; well-done, 170°), basting occasionally with reserved marinade.
