Preheat your oven to 400°F (200°C) and line a baking sheet with parchment paper.
Place the broccoli florets on the baking sheet, drizzle with 0.5 tsp of olive oil, and sprinkle with a pinch of sea salt.
Roast the broccoli for 15-20 minutes until the edges are slightly charred and tender.
While the broccoli roasts, cut the chicken breast into 1-inch bite-sized cubes.
In a small bowl, toss the chicken cubes with the arrowroot powder, sea salt, and black pepper until evenly coated.
Heat the remaining 1 tsp of olive oil in a non-stick skillet over medium-high heat.
Add the chicken to the skillet and sear for 5-6 minutes, turning occasionally, until golden brown and cooked through.
In a small jar, whisk together the fresh orange juice, coconut aminos, grated ginger, and minced garlic.
Reduce the skillet heat to medium and pour the orange sauce over the chicken.
Simmer for 2-3 minutes, stirring constantly, until the sauce thickens into a glossy glaze that coats the chicken.
Plate the roasted broccoli and top with the crispy orange chicken, drizzling any remaining glaze from the pan over the top.
