To a small plastic bag (or sealable container), add Spice Mix and whisk to combine. Set aside. Add Marinade Ingredients to a large freezer bag and whisk to combine. Add 3 tablespoons Spice Mix to Marinade and whisk to combine. Add steak and seal bag, removing excess air. Marinate in the refrigerator 4-12 hours. When ready to grill, mix remaining Spice Mix with 2 tablespoons olive oil to create a Spice Rub. Discard marinade and pat steaks dry with paper towel (just so steak is not wet, not to remove marinade/spices). Rub steak evenly all over with Spice Rub and let rest at room temperature for 30-60 minutes. Grease and preheat outdoor grill to medium-high heat. Grill steak for 7 to 10 minutes per side, turning once, for medium-rare. For medium or medium well, continue cooking steak over indirect flame for an additional 5-10 minutes per side, depending on thickness. *If you like your steaks rare then use HIGH heat so you can get the charred outside in less time. Remove steak and let rest 10 minutes before <em>thinly</em> slicing against the grain on a diagonal.
