Preparation

Heat oil in a sauté pan over medium heat.

Add potatoes, scallions, eggs, and cheese.  Season with salt and pepper.

Lower heat and move mixture around with a wooden spoon so that it cooks evenly.

Once tortilla is set, slide it out onto a plate to turn it over.  Cook on the other side until done.

Let cool to room temperature.  Slice in wedges and serve.
