Preheat oven to 375'.
Cut each tortilla into fourths or eighths depending on how small tortillas are and how big you want chips to be. Easily stack multiple tortillas to cut more than one at a time.
Spread out the chips on a baking pan. You may need to use 2 baking pans, or just bake in batches if you're making a lot.
Use a basting brush, or drizzle olive oil over tortillas and use your hands to evenly cover chips in a very thin layer of olive oil.
Sprinkle sea salt on top, however much you desire.
Bake approx. 8-14 minutes. Keep an eye on the chips and remove when you see some starting to get golden brown edging, depending on your oven and sheet being used as well as thickness of tortillas purchased this could take more or less time so it's best to just keep a close eye. You can always taste test one and bake a couple more minutes if desired!
