Use a sharp knife to cut each tortilla into 8 triangles.
For frying
Heat a large, heavy pot over medium-high heat and add the oil to 2-inches in depth. Heat the oil to 350F.
Fry the tortilla wedges in small batches until lightly browned, flipping once during the frying. Remove and drain on paper towels, then sprinkle with salt. Repeat the process until all of the chips are fried.
For baking
Brush the tortillas with oil.
Bake the chips, in a single layer, in the oven at 350 degrees.
Watch the chips closely and cook until golden brown. Stir at least once while they are cooking.
For the air fryer
Preheat the air fryer to 350 degrees.
Brush the tortillas with oil. Put the chips in the air fryer basket and cook for 5 - 8 minutes until golden brown.
Stir the chips 1 to 2 times while they cook. Do not overload the air fryer basket.
Cool the tortilla chips slightly before serving.
Notes
Don't forget to salt the chips after they are done cooking but while they are still hot!
