Preheat your oven to 400°F (200°C) and line a baking sheet with parchment paper.
Cut the chicken breast into bite-sized cubes and toss them in a bowl with avocado oil, sea salt, and black pepper.
Spread the chicken on the baking sheet and bake for 15-18 minutes until cooked through and slightly golden.
While the chicken bakes, whisk together the orange juice, coconut aminos, honey, grated ginger, minced garlic, and arrowroot powder in a small saucepan.
Place the saucepan over medium heat and whisk constantly until the sauce simmers and thickens into a glossy glaze.
Steam the broccoli florets until tender-crisp and lightly sauté the cauliflower rice in a non-stick pan until heated through.
Toss the baked chicken cubes into the orange glaze until every piece is well-coated.
Serve the glazed chicken over the cauliflower rice with the steamed broccoli on the side.
