Trim the fat from steak. Place steak in a plastic bag and set the bag into a shallow dish. For marinade, in a small bowl stir together oil, lime juice, jalapeno peppers, shallots, cilantro, garlic and salt. Pour over steak, seal bag. Marinate in the refrigerator for 6 hours or overnight, turning the bag occasionally.
Drain steak, reserving marinade. Grill steak on an uncovered grill directly over medium coals to desired doneness, turning once. Allow 14 to 16 minutes for medium rare or 18 to 20 minutes for medium. Brush occasionally with marinade up to the last 5 minutes of grilling.
