Prepare the sauce by combining in a small bowl and set aside.
Season the chicken with salt and pepper and toss to coat in arrowroot starch. Set aside.
Using a large pan, heat the oil over medium heat. Add the vegetables and saute for 6-7 minutes or until tender. Set aside.
Add more avocado oil if needed to the pan and bring to medium-high heat. Add the chicken in a single layer, being careful to not allow the chicken to touch too much to ensure it crisps well (cook in batches if needed). Cook for 3-4 minutes on each side or until the chicken is cooked through to 165 F. Set aside
Add the garlic and ginger to the pan and cook for 1-2 minutes or until lightly fragrant. Add the sauce and stir to remove any browned bits from the bottom of the pan. Allow to heat for 2-3 minutes to thicken.
Stir in the cooked chicken and vegetables and stir to coat in the thickened sauce.
Serve topped with green onion over rice or cauliflower rice!
