01 - Set your grill to medium-high heat, targeting approximately 400°F. Allow the grates to fully heat before placing any food.
02 - Peel the sweet potatoes if desired, then slice them into 1/2-inch thick rounds for even cooking and optimal grill contact.
03 - Place the sweet potato slices in a large bowl, drizzle with olive oil, and toss thoroughly until every slice is evenly coated.
04 - In a small bowl, combine the smoked paprika, garlic powder, sea salt, and black pepper. Sprinkle the mixture over the oiled sweet potatoes and toss again until the seasoning is uniformly distributed.
05 - Arrange the seasoned slices on the grill in a single layer. Cook for 6 to 8 minutes per side until distinct grill marks develop and the flesh is fork-tender.
06 - Transfer the grilled sweet potatoes to a serving platter. Finish with chopped fresh cilantro, a sprinkle of flaky sea salt, and a squeeze of fresh lime juice. Serve immediately while hot.
