Dice chicken into 1-inch cubes.
In a bowl, toss chicken with arrowroot starch, sea salt, black pepper, garlic powder, and ginger powder until evenly coated.
In a small jar, whisk together coconut aminos, rice vinegar, honey, and sesame oil to create the sauce.
Heat avocado oil in a large skillet or wok over medium-high heat.
Add the chicken to the skillet and cook for 5-7 minutes until golden brown and crispy on all sides.
Remove chicken from the skillet and set aside.
In the same skillet, add the bell pepper, sugar snap peas, and pineapple chunks; sauté for 3-4 minutes until the vegetables are tender-crisp.
Return the chicken to the skillet and pour the sauce over the mixture.
Stir constantly for 1-2 minutes until the sauce thickens and coats everything beautifully.
While the stir-fry finishes, steam the cauliflower rice in a separate pan or microwave until tender.
Serve the crispy chicken and vegetable mixture over the cauliflower rice.
