Preheat oven to 300 degrees F.
Leave the skin on! Thinly slice radishes, beets, and sweet potatoes or use a mandolin, place in a bowl.
Toss with oil (olive, coconut etc.), salt and pepper (and herbs and garlic) if you like!
Lay onto baking sheets, use parchment paper if you have it. Don't overlap.
Bake for 12-15 minutes. Time depends on thickness.
Note: The beets have a tendency to bake faster so watch them. After drying you will have a crispy fun treat! Store in an airtight container up to a week.
