What do you call a steak separated with fork?
Shredded is the correct term...maybe ropa vieja? This dish is typically made with flank steak that is shredded with the grain of the meat.  The Mexican version is cooked, shredded and then browned, usually in a pan on the stove, but back on the grill does not seem unreasonable.  It is typically served in a tortilla, with condiments.
