Spray a large skillet or cast iron pan liberally with avocado oil spray. Place on medium-high heat.
Season the chicken with salt, then add the chicken pieces to the hot skillet and cook for 4-5 minutes on each side or until golden brown and cooked through. Add the garlic and ginger to the pan and cook for 30 seconds.
While the chicken is cooking, whisk together the bourbon, brown sugar, maple syrup, ketchup, vinegar, water, coconut aminos and cornstarch in a medium bowl or liquid measuring cup.
Pour the sauce mixture over the chicken and bring to a boil. Turn the heat down to low and simmer for 3-5 minutes or until sauce has thickened.
Sprinkle with green onions and serve immediately, over rice if desired.
