Colombian Churrasco (Grilled Sirloin Steak)

In some countries Churrasco is made from filet mignon, skirt steak, or beef tenderloin and pounded thin. In Colombia is made from lean sirloin (my grocery calls it London Broil cut) and it is about 1 to 1 1/2 inches thick. It’s marinated in a chimichurri sauce then grilled or broiled.
