This is my default side dish. It's yummy, healthy, and the kids will eat it since they're "fries." It can easily be adjusted by using more sweet potatoes.
Sweet Potato Fries
2 medium sweet potatoes
Preheat oven to 425F. Peel the sweet potatoes, then julienne into 1/8"-thick fries. Spray a baking sheet with cooking spray. Spread the fries in a single layer on the sheet, then spray with more cooking spray. Lightly salt the fries.
Bake for 10 minutes at 425F. Turn fries over, then bake an additional 5-10 minutes. Serves 4.
