Cut the chicken breast into 1-inch bite-sized cubes and place them in a bowl.
Toss the chicken with arrowroot powder, sea salt, and black pepper until evenly coated.
In a small glass jar, whisk together the coconut aminos, rice vinegar, honey, tomato paste, grated ginger, and minced garlic to create the sauce.
Heat the avocado oil in a large skillet or wok over medium-high heat.
Add the chicken to the skillet in a single layer and sear for 3-4 minutes per side until golden brown and crispy.
Add the sliced bell peppers, snap peas, and pineapple chunks to the skillet with the chicken.
Stir-fry the vegetables for 2-3 minutes until they are tender-crisp and vibrant.
Pour the sauce over the chicken and vegetables, stirring constantly as it bubbles and thickens into a glossy glaze.
Once the sauce has coated everything evenly, remove from heat.
Serve the crispy chicken and vegetables over the warm jasmine rice.
