Bring this easy cold sweet potato salad to your next barbecue. It's naturally sweet from the roasted sweet potatoes, with a chipotle lime kick from the easy dressing recipe.
Preheat oven to 350 degrees. Spread sweet potatoes in a single layer on a rimmed baking sheet lined with parchment paper. Drizzle with olive oil and sprinkle with a pinch of sea salt.
Roast sweet potatoes for 30-40 minutes, or until tender, stirring halfway through.
Whisk chipotle lime mayo, lime juice, and remaining sea salt together in a large mixing bowl. Stir in red onion, red pepper, and celery.
Toss cooked sweet potatoes in mayonnaise mixture. Fold in cilantro. Refrigerate to meld flavors.
