Whole wheat pita bread
Cut pita bread into small triangles and separate front from back (to double the amount and allow the now-thinner pita bread to bake to a better crispiness); drizzle with olive oil and bake at 350* for about 5 minutes; after first 5 minutes, flip pita chips over to continue baking for an additional 5 minutes - be careful to watch them to prevent burning, and enjoy!
