Take meat out of fridge and set on counter to come up to room temp. Brush with canola oil and top with pepper and oregano, if desired. You may also rub the meat with a cut clove of garlic.
Light charcoal in grill. Once outsides turn white, spread into an even layer and add 2 good handfuls of hickory wood chips. Let the wood chips burn down so the flames aren't huge, then add your meat to the grill.
Sprinkle with as much salt as desired. Cook 3-5 minutes then flip. Sprinkle with more salt. Cook until meat is cooked to your liking.
Remove from heat and cover with foil to rest 10-15 minutes. Cut across the grain into very thin strips and serve.
