I keep finding all these fabulous Halloween ideas on different blogs. This one actually came from Martha Stewart, and I love it. Great for any occasion, just choose your cookie cutters accordingly.

24 large flour tortillas (use assorted ones like plain, whole wheat, or sun-dried tomato)

Preheat oven to 350 degrees. Coat a baking sheet with cooking spray. Using a few Halloween inspired cookie cutters, cut shapes from tortillas. Arrange as many shapes as can fit in a single layer on oiled sheet. Coat tortillas with cooking spray, and season with salt. Bake until slightly darkened and crisp, 10 to 12 minutes. Transfer to a wire rack to cool. Repeat with remaining tortilla shapes, using a clean, cooled baking sheet.
