corn tortillas (Wal-Mart's Great Value brand have zero fat)
• Preheat oven to 375.
• Spray tops of tortillas with more cooking spray. This is probably optional, but helps them get more crisp.
• Bake at 375 for 13-15 minutes. (Watch carefully toward the end so they don't burn; baking times really vary depending on how many tortillas are on the pan, how much spray you use, etc. If you are baking 2 pans at a time, it usually takes a little longer.)
The tortillas will shrink a little while cooking, and end up looking like this:
• Remove from oven. Sprinkle with salt (taco seasoning is also good).
• Eat with your favorite salsa and/or guacamole.
