Remove steak from refrigerator and let stand at room temperature until grill has come up to full heat. Place steak on grill and cook for 6-8 minutes per side, depending on thickness, desired doneness and type of steak being used for this recipe. I recommend medium to medium well for this recipe, but you be the judge of that. Halfway through cook time, wrap tortillas in a large piece of aluminum foil. Place onto grill and warm them by indirect heat. Turn every few minutes.
