In a small bowl, whisk together the honey, apple cider vinegar, coconut aminos, and arrowroot powder to create the stir-fry sauce.
Season the diced chicken breast evenly with the sea salt and black pepper.
Heat the avocado oil in a large skillet or wok over medium-high heat until shimmering.
Add the chicken to the skillet and cook for 5-6 minutes, stirring occasionally, until golden brown and cooked through.
Stir in the minced garlic and fresh ginger, cooking for 30 seconds until the aromatics are fragrant.
Add the sliced bell peppers, snap peas, and pineapple chunks to the pan.
Stir-fry the mixture for 3 minutes until the vegetables are tender-crisp and vibrant in color.
Pour the prepared sauce over the chicken and vegetables, tossing constantly until the sauce thickens into a glossy glaze.
Serve the stir-fry immediately over warm brown rice and finish with a drizzle of toasted sesame oil.
