In a large bowl, add the chicken, 2 tbsp of arrowroot flour, 2 tbsp of avocado oil, salt and pepper, and toss.
In a small bowl, add the sauce ingredients and whisk. Set aside.
Heat a non-stick skillet to medium heat and add 1/4 cup avocado oil. Once hot, add the chicken in batches and cook for about 4 minutes per side. Set aside on a plate once finished cooking all the chicken.
Add another tablespoon of avocado oil and add in all the onions and veggies. Cook for about 4 minutes.
Add the chicken back in and pour in the sauce. Cook for another 5 minutes until everything is nicely coated and thick.
Serve on top cauliflower rice or regular rice and top with scallions and extra orange zest.
Enjoy.
