Sweet potatoes are more versatile than you might gather from the holiday-only treatment many people give them. Looking for an unexpected twist? Try lime with these spicy sweet potatoes.
Preheat oven to 400 degrees. Heat a baking sheet in the oven until hot, about 15 minutes. Meanwhile, slice sweet potatoes in half lengthwise; slice each half into 3 wedges. Place in a medium bowl, and toss with oil, cumin, paprika, and ginger. Season with salt and pepper.
When baking sheet is hot, remove from oven. Arrange sweet potatoes in a single layer on sheet. Return to oven; cook until potatoes are crisp and golden on the bottom, about 15 minutes. Turn, and continue cooking until golden all over, about 15 minutes more.
Remove from oven; season with salt and pepper. Serve with limes and sauce.
