Prep the Chicken: In a bowl, toss chicken chunks with arrowroot powder, salt, and pepper. Set aside.
Make the Sauce: In a small bowl, whisk together coconut aminos, arrowroot powder, rice vinegar, minced garlic, chicken broth, ginger, sesame oil, water, and sweetener (if using). Set aside.
Cook the Chicken: Heat 1 tbsp olive oil in a large skillet or wok over medium-high heat. Add chicken and cook for 6–8 minutes, until browned and cooked through. Remove from the pan and set aside.
Sauté Veggies: Add the remaining 1 tbsp olive oil to the pan. Add bell peppers, onion, zucchini, garlic, and dried chili peppers. Cook for 4–5 minutes, stirring often, until veggies are just tender.
Add Chicken & Sauce: Return the cooked chicken to the pan. Pour in the sauce and add cashews and most of the green onions. Stir everything together and cook for 2–3 more minutes, until the sauce thickens and coats everything.
Serve & Garnish: Serve over cauliflower rice if desired. Garnish with extra green onions, chopped cashews, and crushed red pepper flakes if desired.
