Cut the chicken into bite-sized pieces and toss in a bowl with the sea salt, black pepper, and arrowroot starch until evenly coated.
In a small jar, whisk together the pineapple juice, coconut aminos, rice vinegar, honey, minced ginger, and minced garlic to create the sauce.
Heat the avocado oil in a large skillet or wok over medium-high heat until shimmering.
Add the chicken to the pan and sear for 5-6 minutes, turning occasionally, until the exterior is golden and crispy.
Toss in the broccoli, bell pepper, and snap peas, stir-frying for 3-4 minutes until the vegetables are bright and crisp-tender.
Pour the sauce over the chicken and vegetables, tossing constantly for 1-2 minutes until the glaze thickens and coats everything beautifully.
Serve the stir-fry immediately over the cooked white rice.
