Preheat oven to 400 F. Line a baking sheet with aluminum foil. Set aside.

In a large bowl, combine garlic, ginger and salt. Place chicken in a single layer on the prepared baking sheet. Bake chicken for 30 minutes, flipping the chicken after 15 minutes.

Meanwhile, after the chicken has been cooking for about 20 minutes, heat soy sauce, sugar and pineapple in a small pot, over medium high heat. Boil the sauce until it has thickened slightly, about 10 minutes.

Remove chicken from oven, but do not turn off oven. Flip the chicken over and brush the tops of the chicken wings with the teriyaki sauce. Bake for 5 minutes. Flip the chicken pieces over and brush the other side of the chicken with the sauce. Bake for another 5 minutes.

Serve hot, with remaining sauce.
