Pat the chicken breast dry with paper towels and cut into bite-sized pieces.
Place the chicken in a bowl and toss with arrowroot powder, sea salt, and black pepper until evenly coated.
In a small mixing bowl, whisk together the fresh orange juice, coconut aminos, honey, minced ginger, and minced garlic to create the sauce.
Heat the sesame oil in a large non-stick skillet over medium-high heat.
Add the chicken to the skillet and cook until golden brown and crispy on all sides, approximately 6 to 8 minutes.
Add the broccoli florets to the pan along with a tablespoon of water, then cover with a lid to steam for 3 minutes until tender but still bright green.
Remove the lid and pour the orange sauce over the chicken and broccoli.
Stir constantly for 1 to 2 minutes until the sauce thickens into a glossy glaze that coats everything beautifully.
Garnish with fresh orange zest and serve immediately.
