In a large mixing bowl, combine the cut chicken with the cornstarch. Leave this mixture for 5 minutes so that the cornstarch velvets the chicken.
Rinse the cornstarch off of the chicken and dry the chicken pieces.
Heat avocado oil to a large cast iron skillet over medium heat.
Once the skillet is hot, add the chicken. Cook for 5-10 minutes, tossing to prevent the chicken from sticking to the skillet.
When the chicken is completely cooked through, remove to a plate and lightly cover with foil to keep warm.
In a medium mixing bowl, combine ginger, onion powder, crushed red pepper, garlic, soy sauce, rice vinegar, brown sugar, bourbon, chicken broth, and cornstarch.
Pour the ingredients into the cast iron skillet and bring the mixture to a simmer, stirring often.
Once the sauce has slightly reduced and thickened (about 10 minutes), add the chicken back into the sauce.
Stir to coat the chicken pieces with sauce. Serve immediately with hot fluffy white rice.
