Stir together the yogurt, lime juice, green onions and cilantro. Season to taste with salt and set aside.
In a large bowl, toss the chicken wings with the olive oil and salt and pepper.
Arrange the chicken wings in a single layer on the sides and bottom of the preheated pan. Cover the grill and cook, turning and rearranging the wings in the pan two or three times to ensure even cooking, until well browned and cooked through, about 25 minutes.
Pour half of the hot sauce over the wings and toss.
Pour the remaining hot sauce on the wings, toss again and cook 1 to 2 minutes more.
Transfer the wings to a large bowl and serve immediately with the cilantro–green onion dip alongside.
