Preheat the oven broiler. IN a bowl, toss the chicken wings with the oil and season with salt & pepper. Arrange the wings on a rack set over a baking sheet and broil 10-12 inches from heat for about 45 minutes, turning once or twice, until golden, crisp, and cooked through. If sesame seeds are not already toasted, use a little oil in a separate skillet and toast the sesame seeds over medium heat until roasted, ~5 minutes Meanwhile, in a blender, combine the rice vinegar with brown sugar, tamari sauce, Mae Ploy sweet chile sauce, Sriracha sauce, Frank's hot sauce, ginger and half of the scallions and puree until smooth. Transfer the sauce to a large saucepan and boil over high heat until thick and glossy, ~5 minutes. Add the chicken wings to the sauce and cook, tossing gently, until glazed, ~3 minutes Transfer the wings to a platter and garnish with remaining scallions and sesame seeds.
