Make up the marinade using the above listed ingredients.
Combine steak and marinade in plastic food storage bag. Push out all air; secure with twist-tie and marinate for up to an hour.
Remove steak from marinade; wipe with a paper towel to remove any bits that may burn. Broil 4 inches from heat for 8 minutes without turning, or until desired doneness (internal temperature of 125 degrees F. for rare).
Let stand 5 minutes. Slice thinly across the grain.
