In a medium skillet, add 1/4 inch oil and place over medium-high heat. Once it is hot, anywhere from 4 to 6 minutes, add tortilla pieces. When you add a tortilla to the oil, it should immediately start to bubble. Fry, stirring and flipping occasionally, until they achieve a golden tan and slightly brown color and are hard and crispy. Remove with a slotted spoon and place on a plate covered with paper towel. Sprinkle with salt to taste.
