1 sweet potato, peeled
2 tbsp olive oil
1 1/2 tbsp tamari
1 tsp toasted sesame oil
1/4 tsp cayenne pepper (or to taste — this might be too spicy for some as the dehydration concentrates the kick!)

Slice sweet potato as thinly as possible using mandolin.
Add sweet potato slices to medium-sized bowl and add olive oil, tamari, sesame oil and cayenne pepper. Massage the ingredients into the sweet potato.
Lay out sweet potato slices on dehydrator trays.
Dehydrate on high overnight or until crunchy.
