I've recently become addicted to sweet potato fries, especially since they are so good for you. :)
1 sweet potato
Preheat oven to 350F. Peel and cut sweet potato into planks of similar size. Toss them in olive oil, salt and pepper. Line a cookie sheet with parchment paper and arrange sweet potatos on the cookie sheet in a single layer. Bake for 20 minutes, turn them, then bake for another 20 minutes or until done but not burnt.
