Preheat oven to 425 degrees. Line sheet tray with parchment paper (for easier clean up).
Pat the wings with paper towels to dry if wet. Place on sheet tray in a single layer and season with salt and pepper. Drizzle with oil and toss to coat.
Bake for 30 minutes.
Meanwhile, mix the remaining ingredients (except the garnishes) in a bowl and mix well.
Remove the wings from the oven and reduce the heat to 375 degrees.
Pour the sauce over the wings and place back in the oven for another 30 minutes, flipping halfway through (after about 15 minutes).
Remove from the oven and plate right away with green onions and sesame seeds to garnish.
