Dice the chicken breast into bite-sized pieces and toss in a bowl with sea salt, black pepper, and arrowroot starch until evenly coated.
Heat the avocado oil in a large skillet or wok over medium-high heat until it begins to shimmer.
Add the chicken to the skillet in a single layer and sear until golden brown and cooked through, about 5-6 minutes, then remove and set aside.
In the same skillet, add the sliced bell peppers, snap peas, and pineapple chunks, sautéing for 3-4 minutes until the vegetables are tender-crisp.
Stir in the minced garlic and grated fresh ginger, cooking for 30 seconds until the aroma is released.
Whisk together the coconut aminos, rice vinegar, and honey in a small bowl, then pour the mixture into the skillet.
Return the cooked chicken to the pan and toss everything together for 1-2 minutes until the sauce thickens into a glossy glaze.
Serve the hot stir-fry immediately over the portioned cooked jasmine rice.
