Cut chicken breasts into 1-inch pieces, add to large bowl and sprinkle with salt, pepper, and Xanthan gum. Mix well (I recommend using your hands), ensuring that chicken is evenly coated
Brown chicken over medium high heat in coconut and sesame oil, allowing to brown and crisp on one side before flipping and crisping on the other side. Remove from pan and set aside
Add liquid aminos, ground ginger, garlic powder, stevia, and vinegar to pan and whisk together. Taste and adjust for sweetness
Allow liquid mixture to come to a simmer, then add chicken and mix well over low heat. The Xanthan gum will cause the liquid to thicken and stick to the chicken
Serve immediately, or allow to cool to portion for meal prep
