In a small bowl, whisk together the honey, apple cider vinegar, coconut aminos, and arrowroot starch to create the sweet and sour sauce base.
Cut the chicken breast into bite-sized cubes and season evenly with sea salt and black pepper.
Heat the toasted sesame oil in a large skillet or wok over medium-high heat until shimmering.
Add the chicken to the skillet and sauté until golden brown and cooked through, approximately 5-7 minutes.
Remove the cooked chicken from the skillet and set aside on a plate.
In the same skillet, add the minced garlic and grated ginger, sautéing for 30 seconds until fragrant.
Add the sliced bell peppers and sugar snap peas to the skillet, cooking for 3-4 minutes until they are tender-crisp.
Stir in the fresh pineapple chunks and cook for 1 minute to warm through.
Return the chicken to the skillet and pour the prepared sauce over the mixture.
Toss everything together for 1-2 minutes until the sauce thickens and glazes the chicken and vegetables.
Serve the hot stir-fry immediately over a bed of steamed cauliflower rice.
