Sweet Potato Fries

2 sweet potatoes (about 1 lb each)
1 tablespoon olive oil
1/2 teaspoon chili powder
1/2 teaspoon garlic powder
1/4 teaspoon salt, plus more for sprinkling
Juice of 1/2 lime


1. For the sweet potato fries, preheat the oven to 425 degrees.

2. Wash and dry the potatoes and, with the skin on, slice into 1/2-inch-thick rounds; cut the rounds into 1/2-inch-thick finger-shaped pieces. Toss the potatoes in a bowl with the oil, chili powder, garlic powder and salt.

3. On a baking sheet, spread the sweet potato fries in a single layer and roast, stirring every 10 minutes, until brown and tender, 30 to 35 minutes. Remove from the oven, transfer to a platter or bowl and sprinkle with a little more salt (sometimes they don't need more salt so taste before adding more salt) Then spinkle with the juice of 1/2 a lime.
