As a marinade I use Worcesteshire Sauce, A1, and Garlic Pepper shake. Perferate the steak a few times with a fork. Put all ingredients together in a pan, mix it up good. Place steak in the pan, leave in fridge covered for 4 hours. Flip it, leave it in for two hours. Grill it. This I usually use on lower grade cuts. For higher grade cuts like Rib Eye, NY Strip, and T-Bone I sprinkle salt and fresh ground peppercorn, and enough Filippo Berio ExtraVirigin Olive Oil on the steak to give it a nice shine. Grill for about 3 minutes on both sides, depending on the thickness of the cut.
