Cut tortillas, paint them with a little of olive oil, or any other vegetable oil you have at home (optional) and put them on a baking tray with baking paper.
Preheat the oven and bake tortillas for 5 minutes at 390ºF or 200ºC in the middle rack of your oven. Take them out of the oven and let them cool, so they can get crunchy.
Put all spices in a food processor and blend to combine.
Mix the spices with tortilla chips (you can spread the spices with your fingers on the chips) and serve.
