This Portuguese dish is the forefather of Brazilian Churrasco, which goes back to the days when Portugal was a major world player (read: a very, very long time ago.) Espetada is typically served with skewers of tomato, onion, and/or zucchini or other squashes. This preparation deals exclusively with the meat. I however, think that onion and tomato are important to the success of this dish. Especially the tomato. Rub a bit of the charred stuff on some bread which has been soaked in the meat juice. You will thank me for it, I promise.
