• Using a blender or food processor, mix all of the ingredients together (minus the flank steak). Give it just a few pulses, you don't want the marinade completely pureed (just enough to mix it all).
• Pierce the flank steak with a fork, making sure to pierce it on both the front and the back so that the steak can soak up the flavours of the marinade.
• I like to put the steak and the marinade into a ziplock bag to marinate, but you can use any dish or bowl that you like. Cover the steak in the marinade, making sure to coat both sides.
• Massage the bag so the steak is completely coated in the marinade.
• Let the steak marinade in the bag, in the refrigerator for at least 4 hours, but overnight is best.
• Right before you are ready to grill, give the steaks one last good massage in the marinade.

Time to barbecue:

• Preheat your barbecue on the highest setting.
• NOTE:  Marinated flank steak on the barbecue is easy to do, BUT it will flare the first time you set it on the grill! Please beware!! I'm talking full on flames! See picture above...
• With the barbecue on hight heat, sear both sides, then cook for approximately 7 minutes on each side, so roughly 15 minutes total. We like ours slightly pink inside, so you may want to cook yours longer.
• After you remove it from the grill, cover the steak with tin foil, and let it rest for about 5 minutes.
• When ready to serve, slice the steak thinly across the grain of the meat.
• Enjoy!
