Tortilla chips fry better when the tortillas are a LITTLE dried out. Lay out on paper towels or wax paper for a few hours before cutting. Or you can dry them in the oven, by laying out in a single layer on a baking sheet and baking at 200 for 10 minutes.
Cut each tortilla into 6 triangle shaped wedges.
Add oil to your skillet and fill to about ¼ inch high on the sides and cook on Medium heat. You can test the heat of the oil by adding a small piece of tortilla to it and it sizzles (you want it around 350 degrees).
Fry the tortilla pieces in batches (you want them to change color just lightly - not browned - and get crispy) making sure to place on a paper towel lined plate when done. Sprinkle with salt while warm.
