Preheat oven to 375 degrees. Slice radishes into very thin chips and spread on a cookie sheet that has been sprayed with non-stick cooking spray. Lightly mist radish slices with cooking spray and then sprinkle with salt and pepper. (if using other seasonings, now is the time to add them). Bake for 10 minutes, flip, and bake for another 5-10 minutes or until crisp. Time may vary so watch these after flipping.
