Mexico is a part of North America [1]. What is less obvious is whether Guatemala, Belize, Nicaragua, etc, would fall into N or S America. Central America is a region, like the Middle East, but is not its own continent. Central America is a part of North America [2].

Sear each side, flipping minimally. It should not take long for a crisp brown crust to form. Depending on the heat of your pan, it should take about 2-4 minutes (or less) for each side to finish cooking. When the first side is done, flip your steak and cook the second side for about as long.
Season the steaks with the salt and pepper. Add 1 tablespoon of the oil to the pan, and, once hot, place 2 of the steaks, fat side down, in the hot pan. Sear the steak until well caramelized and most of the fat has rendered, about 5 minutes. Turn the steak over and sear for 5 minutes on the other side.
