Whisk pineapple juice, coconut aminos, rice vinegar, honey, and arrowroot powder in a small bowl to create the sauce.
Cut chicken into bite-sized pieces and season evenly with sea salt and black pepper.
Heat avocado oil in a large skillet or wok over medium-high heat until shimmering.
Add chicken to the skillet and cook until golden brown and no longer pink in the center, then set aside.
In the same skillet, sauté the bell peppers, broccoli, and red onion until they are tender-crisp.
Stir in the minced garlic and fresh ginger, cooking for 30 seconds until the aroma is released.
Return the cooked chicken to the skillet and pour the prepared sauce over the mixture.
Simmer for 1-2 minutes while stirring constantly until the glaze thickens and coats the ingredients.
