Ingredients

  • 1 cup olive oil
  • 3/4 cup soy sauce
  • 1/2 cup balsamic vinegar
  • 1/3 cup fresh lemon juice
  • 2 tablespoons stone ground mustard dry mustard works if you're in a pinch

  • 1 teaspoon ground black pepper
  • 1/4 cup Worcestershire sauce

Instructions

  • Add all ingredients except flank steak to blender and run until smooth, reserve 1 cup for basting and dipping.
  • Pour remaining marinade over steak and refrigerate in a shallow pan or ziploc bag for at LEAST 24 hours. (I like to freeze mine in the marinade for later!)
  • Cook on a medium heat grill, basting continually, for 3 - 5 minutes on each side, or until you reach desired doneness. (This can also be done under the broiler in your oven).
  • Allow to rest 2 minutes before cutting.
  • Enjoy!
