Cut the chicken breast into bite-sized pieces, pat dry with paper towels, and toss in a bowl with arrowroot powder, sea salt, and black pepper until lightly coated.
In a small glass jar or bowl, whisk together the fresh orange juice, orange zest, coconut aminos, honey, minced ginger, and minced garlic to create the glaze.
Heat the avocado oil in a large stainless steel skillet or wok over medium-high heat until shimmering.
Add the chicken to the skillet in a single layer and sear for 3-4 minutes per side until golden brown and cooked through, then transfer chicken to a clean plate.
Add the broccoli florets, sliced red bell pepper, and sugar snap peas to the same skillet with 1 tablespoon of water; cover for 2 minutes to steam-fry until tender-crisp.
Remove the lid, return the chicken to the skillet, and pour the orange glaze over the mixture.
Toss everything continuously for 1-2 minutes until the sauce thickens into a glossy glaze that coats every piece of chicken and vegetable.
