Chipotle-Mango Sirloin Steaks

In 1-quart saucepan, heat nectar to boiling. Cook, stirring occasionally, until reduced to 1/4 cup.

In food processor or blender, pour reduced nectar; add steak sauce and chiles. Cover; process until marinade is smooth.

Place steaks in large freezer plastic bag. Pour marinade over steaks. With fingers, rub marinade onto steaks until coated. Seal bag, removing all air. Refrigerate 8 hours or overnight, or freeze up to 2 months.

If steaks are frozen, place in refrigerator to thaw overnight.

Heat gas or charcoal grill. Remove steaks from marinade; discard marinade. Place steaks on grill over medium heat. Cover grill; cook 10 to 15 minutes, turning once, until desired doneness.
