In a small bowl, whisk together the raw honey, coconut aminos, apple cider vinegar, and arrowroot powder to create the sweet and sour sauce base.
Heat the toasted sesame oil in a large skillet or wok over medium-high heat.
Dice the chicken breast into bite-sized pieces and season with sea salt and black pepper.
Add the chicken to the skillet and sauté until golden brown and cooked through, then remove from the pan and set aside.
In the same skillet, add the sliced red bell pepper, minced garlic, and grated fresh ginger, sautéing for 3-4 minutes until the peppers are tender-crisp.
Add the fresh pineapple chunks to the skillet, cooking for another 2 minutes until they begin to caramelize slightly.
Pour the sauce mixture into the skillet and stir constantly until the liquid bubbles and thickens into a glossy glaze.
Return the cooked chicken to the pan and toss thoroughly to coat every piece in the sauce.
Serve the sweet and sour chicken immediately over the warm, cooked brown rice.
