1. Preheat a grill to medium-high and the oven to 350°F.
2. Place the sweet potatoes in a bowl, and add the 3 tablespoons olive oil, salt, and pepper. Toss well. Then
place the potatoes on the grill and cook until nice grill
marks develop, 2 to 3 minutes on each side.
3. Transfer the potatoes to a baking sheet, place it in the oven, and bake until they are tender enough to easily pierce with a fork, 20 to 25 minutes. Remove from the oven and set aside to cool to room temperature.
4. Arrange the sweet potato slices on a platter, and drizzle the remaining 1⁄4 cup olive oil and the lime juice over them. Sprinkle with the cilantro, red onion, and cheese, and serve.
