Reason #8525265 why LifeHacker.com is awesome. My kids downed the last of the chips while being snowed in during Snowpocalypse 2011, so frying up my own is a great alternative - and much more fresh.
Put at least 1 inch of oil in a deep pan on the stove and turn the heat to medium-high; bring to 350°F. The broader the vessel, the more of these you can cook at once, but the more oil you will use. (They cook very quickly, so don't worry if your pan is narrow.)
Stack the tortillas and cut them, pielike, into 4 to 8 wedges. Fry as many at once as will fit without crowding, turning if necessary. Total cooking time will be about 2 minutes; the chips should not brown but just begin to darken in color. Remove with tongs or a slotted spoon and drain on paper towels or paper bags. Sprinkle with salt and serve hot or at room temperature.
