Heat the oven to 350 F.
Brush the tortillas on both sides with a thin layer of olive oil. Sprinkle with salt or the seasonings of your choice. Arrange the tortillas on 2 baking sheets (or bake them in batches).
The tortillas can be close together, but not touching. Bake on the oven’s center rack for 20 to 25 minutes, rotating the pans after 12 minutes, until slightly puffy and golden brown.
Let cool and break into irregular shapes.
