Preheat broiler to high. All you do is cut corn tortillas into triangles. Place in a single layer on a pan. Spray both sides with cooking spray and sprinkle with salt. (or other seasonings) Bake for 5 minutes, turn over, and bake another 5 minutes.
NOTE: I baked for five minutes on the first side and some of them were already done and starting to get a little too dark. I think you could do 6 ot 7 minutes without flipping them and they would still turn out just fine.
