This zesty mayo dip would also go well with sliced red bell peppers and celery sticks before dinner; it's amazing how many vegetables kids will eat when they're actually hungry.

Yield: Makes 4 servings

3 sweet potatoes (about 1 1/2 pounds), peeled, each cut lengthwise into 8 wedges
2 tablespoons vegetable oil
Kosher salt, freshly ground pepper

1/3 cup mayonnaise
1/4 teaspoon finely grated lime zest
2 teaspoons fresh lime juice
Chopped fresh cilantro (for serving)

Preheat oven to 450°F. Toss sweet potatoes and oil on a foil-lined large rimmed baking sheet; season with salt and pepper.

Roast, turning once, until golden brown and crisp, 25-30 minutes.

Meanwhile, whisk mayonnaise, lime zest, and juice in a small bowl.

Season fries with salt, top with cilantro, and serve with lime mayo for dipping.
