Brazilian-Style Flank Steak with Chimichurri

1 cup of olive oil
1/4 cup lemon juice
1/2 cup chopped parsley
1/4 cup chopped cilantro
2 soup spoons fresh chopped garlic
1 soup spoon dry oregano
1 soup spoon red crushed pepper
Salt to taste
1 large flank steak with fat
4 pounds rock salt

Mix first 8 ingredients in large bowl. Use as marinade or set aside for sauce.
Prepare an open flame grill, charcoal or wood; a medium to high temperature is required and the flames must get very close to the meat. Apply a generous amount of salt to the flank steak without rubbing it, the salt must be loose or the meat will be too salty. Grill meat for 5 minutes each side for medium rare, turning only once. Remove flank steak with large tongs and hit meat with the side of a large knife to eliminate extra salt. Let cool for 2 to 3 minutes before slicing.
