Blend everything for the seasoning blend in a bullet style blender. You can try a normal blender, but I haven't tested it, should be fine though. A spice blender will work too, you just might need to do it in batches.
Dust the Fritos in a large mixing bowl that's light enough to toss them. Dusting is easier with some kind of seasoning shaker. Add as much seasoning as you like, and dig in immediately! Wash down with a Mountain Dew if you wanna relive my teenage years!
