In a small bowl, whisk together the honey, coconut aminos, rice vinegar, and arrowroot powder until smooth to create the sauce.
Cut the chicken breast into bite-sized cubes and season with sea salt and black pepper.
Heat the olive oil in a large skillet or wok over medium-high heat.
Add the chicken to the skillet and sauté until golden brown and cooked through, about 5-7 minutes, then remove and set aside.
In the same skillet, add the sliced bell peppers, red onion, minced ginger, and minced garlic, sautéing for 3-4 minutes until crisp-tender.
Return the chicken to the pan along with the pineapple chunks.
Pour the sauce over the mixture and stir constantly for 1-2 minutes until the glaze thickens and coats everything evenly.
Serve the sweet and sour chicken over a base of warm cooked brown rice.
