Cut chicken breast into 1-inch cubes and season with sea salt and black pepper.
Toss the chicken cubes in arrowroot powder until evenly coated.
In a small bowl, whisk together pineapple juice, coconut aminos, apple cider vinegar, honey, minced ginger, and minced garlic.
Heat avocado oil in a large skillet or wok over medium-high heat.
Add chicken to the skillet and cook until golden brown and crispy on all sides, about 6-8 minutes.
Remove chicken from the pan and set aside.
Add sliced bell peppers and snap peas to the same skillet, sautéing for 3-4 minutes until tender-crisp.
Pour the sauce into the skillet with the vegetables and let it simmer for 1 minute until it begins to thicken.
Return the crispy chicken to the pan, tossing everything together until well-coated and heated through.
