Heat your oven to 400F. Spray a baking sheet with cooking spray.
Cut several 8" tortillas (flour or corn) into pie-shaped wedges. Lay the wedges in a single layer on the baking sheet. Spray them generously with olive oil cooking spray. Sprinkle them with ground cumin, paprika, and onion salt. Bake for 5 minutes or until lightly browned and crispy.
Note: you can use chili powder instead of cumin and paprika.
