Preheat oven to 350. Place salt in small bowl and juice from lime (about 1/4 cup).
Brush both sides of the whole tortillas with the bacon fat. Cut into fourths (or how small you want them). Place on metal pan and brush with the lime/salt mixture. Don't overlap the tortillas. Bake 10-14 minutes, turning over halfway through. Repeat with the remaining tortillas.
You can season to your own liking, using more or less salt in the lime mixture (if any at all). I have also used olive oil instead of the bacon grease and it works just fine.
