In a small bowl, whisk together the honey, apple cider vinegar, tomato paste, and coconut aminos until smooth to create the sauce.
Heat the avocado oil in a large skillet over medium-high heat.
Season the chicken cubes with sea salt and black pepper, then add them to the skillet.
Cook the chicken for 5-6 minutes until golden brown and cooked through, then remove from the pan and set aside.
In the same skillet, add the bell peppers, red onion, minced ginger, and minced garlic, sautéing for 3-4 minutes until the vegetables are crisp-tender.
Add the pineapple chunks to the skillet and cook for another 2 minutes until they begin to caramelize slightly.
Return the chicken to the pan and pour the prepared sauce over the mixture.
Toss everything together for 1-2 minutes until the sauce thickens and coats the chicken and vegetables evenly.
