This Grilled Sweet Potato Salad Is Perfect All Summer Long

1. In a medium bowl, whisk olive oil, lime juice, salt, 1/2 teaspoon black pepper, and cayenne pepper to combine. Stir in scallions; set aside.
   

2. Place sweet potato slices in a medium saucepan and add enough water to cover by 1 inch. Bring to a boil over medium-high heat. Reduce heat to medium-low, and simmer sweet potatoes until they can be easily pierced with a paring knife, about 10 minutes. Using a colander, drain potatoes. Lay sweet potatoes out on a large plate or 13- by 18-inch rimmed baking sheet. Brush with olive oil and season with salt and pepper. Set aside.
   

3. Rub corn all over with butter and season with salt and pepper. Wrap tightly in aluminum foil.
   

4. For a Charcoal Grill: Open bottom vent completely. Fill a large chimney starter 3/4 way full with charcoal briquettes (about 4 quarts coal) and light briquettes. When top coals are partially covered with grey ash, pour in an even layer over half of the grill grate. Set cooking grate in place, cover, and open lid vent fully. Heat covered until grill is hot, 5 minutes.

5. For a Gas Grill: Turn all burners to high, cover grill and heat until hot, about 15 minutes. Leave primary burner on high heat, and turn off other burners.

6. Using tongs, place sweet potatoes, corn, and poblano pepper on grill. Cook sweet potatoes until nicely browned on both sides, about 7 minutes per side. Cook corn until tender, about 20 minutes, turning every 5 minutes. Cook poblano until charred all over, turning occasionally, about 15 minutes. Place poblano pepper in bowl, cover tightly with plastic wrap, and let sit until cool enough to handle, about 15 minutes.

7. Remove sweet potatoes and corn to cutting board and let cool slightly. When cool enough to handle, cut sweet potatoes into 1/2-inch cubes and transfer to a large bowl. Cut corn kernels off cob and transfer to bowl with sweet potatoes. Using your hands, remove charred skin, stem, and seeds from poblano pepper; discard. Finely dice pepper and transfer to bowl with potatoes and corn.

8. Pour dressing over sweet potatoes, corn, and pepper and toss to combine. Let sit until flavors meld, about 10 minutes, and season to taste with additional salt, pepper, and lime juice.
