Banana Chips. Slice banana into thin chips, dip in lemon juice, and spread on a cookie sheet. Bake for 2 hours @ 200 degrees and flip. Bake for another 1.5-2 hours or until crisp. (They wont be totally crisp in the oven, but will harden as they cool) IMPORTANT STEP: Spray the cookie sheet with PAM otherwise you will get banana chunks glued to your pan. Enjoy!
