1 tablespoon olive oil
1 tablespoon sea salt
1 teaspoon garlic powder
1 teaspoon (more or less to taste) {chipotle pepper powder}
2  Yukon gold potatoes, sliced in spears (no need to peel)
2  sweet potatoes, sliced in spears (no need to peel)

Preheat oven to 450 degrees.

Stir together the olive oil and seasonings in a large bowl. Add the potatoes and toss until covered. Spread in single layer in a roasting pan (or two if necessary). Roast until tender and lightly browned, about 30 minutes, stirring once half way through cooking. Serve with catsup or aioli.
