a good high quality piece of meat is being wasted if you put anything more than SALT, Pepper and OLIVE OIL on it. It doesn't need anything more than this unless it some butt cutt low grade meat, then yes you want to marinate it, soak it, grill it, then toss it out and eat the grill. Most restaurants will never put more than OO and S&P on it. I prefer MR to Rare as this makes it TENDER and you get the FLAVOR of the meat. If you do want to cook a steak slow, use off-seat cooking method and you can make the toughest butt cutt meat tender. My freind from Columbia showed me a way to cook off the direct heat and uses peppers, onions, etc and throws those dirrectly on the fire and the meat AWAY from the fire. Do not sear it for slow cooking method. We did this with Sirloin one time and it was more tender than a filet mignon.
