If you want to make your own tortilla strips, preheat the oven to 350 degrees F. Cut corn tortillas in half and then crosswise into thin strips. Place the strips in a bowl or a ziploc bag and toss with about a tablespoon of vegetable oil. Arrange them in a single layer on a baking sheet, sprinkle with salt, and bake for 15-20 minutes until crisp and lightly browned.
