Preheat your oven to 400°F (200°C) and line a large baking sheet with parchment paper.
Peel and dice the sweet potato into 1/2-inch cubes. Toss the sweet potato and broccoli florets with half of the avocado oil, sea salt, and black pepper.
Spread the vegetables in a single layer on the baking sheet and roast for 20-25 minutes until the sweet potatoes are tender and caramelized.
While the vegetables roast, cut the chicken breast into bite-sized pieces and toss them in a small bowl with the arrowroot powder until lightly coated.
In a small jar, whisk together the honey, coconut aminos, and minced garlic to create the glaze.
Heat the remaining avocado oil in a non-stick skillet over medium-high heat. Add the chicken and sear for 5-6 minutes until golden brown and cooked through.
Pour the honey-garlic sauce into the skillet with the chicken. Simmer for 1-2 minutes, stirring constantly, until the sauce thickens into a glossy glaze that coats the chicken.
Plate the crispy glazed chicken alongside the roasted sweet potatoes and broccoli, drizzling any remaining sauce from the pan over the top.
