Here's a quick way to serve sweet potatoes as a side.
Preheat the oven to 450
Peel and slice the potatoes, making sure they are equal in thickness for even cooking. Toss them in Olive Oil and spread them out evenly on a baking sheet. Season with Chili pepper and salt. These are not spicy at all, if you like more of a kick add a little cayenne.
Bake for 15 minutes, then toss the potatoes and bake for about 10 more.
