Dice the chicken breast into 1-inch cubes and toss in a bowl with arrowroot powder, sea salt, and black pepper until lightly coated.
In a small jar, whisk together the fresh orange juice, coconut aminos, honey, minced ginger, and minced garlic to create the glaze.
Heat the avocado oil in a large non-stick skillet or wok over medium-high heat until shimmering.
Add the chicken to the hot pan in a single layer and sear for 5-7 minutes, turning occasionally until the edges are golden and crispy.
Add the broccoli florets and sliced red bell pepper to the skillet, stir-frying for 3-4 minutes until the vegetables are bright and tender-crisp.
Pour the orange glaze over the chicken and vegetables, tossing constantly for 1-2 minutes until the sauce thickens into a glossy coating.
Remove from heat and serve immediately while the chicken is at its peak crispness.
