Pat the chicken breast dry and cut into 1-inch cubes.
In a bowl, toss the chicken with arrowroot powder, sea salt, and black pepper until evenly coated.
Whisk together coconut aminos, rice vinegar, honey, minced ginger, and minced garlic in a small bowl to create the sauce.
Heat avocado oil in a large skillet over medium-high heat until shimmering.
Add the chicken to the skillet, cooking for 5-6 minutes until golden brown and crispy on all sides.
Add the sliced bell peppers and pineapple chunks to the skillet, sautéing for 3 minutes until the peppers are tender-crisp.
Pour the sauce over the mixture and stir constantly for 1-2 minutes until the glaze thickens and coats everything beautifully.
Serve immediately while the chicken remains perfectly crisp.
