Preheat oven to 400 degrees F. Grease a heat proof rack with nonstick spray and place over a foil lined rimmed baking sheet. Pat wings dry with paper towels and sprinkle each side with salt and pepper. Place on prepared rack. Bake for 30 minutes.
Meanwhile, make the pineapple teriyaki sauce: heat a saucepan over medium low heat. Add all ingredients except for the sesame seeds and bring to a simmer. Simmer for 10 to 15 minutes, until thickened and slightly syrupy. Stir in sesame seeds. Set aside.
Remove chicken wings from oven and brush both sides with pineapple teriyaki sauce. Cook another 10 minutes then brush again with sauce. Cook 5 more minutes then remove from oven.
