Pat the chicken breast dry with paper towels and cut into 1-inch bite-sized cubes.
Season the chicken cubes evenly with sea salt and black pepper.
In a small mixing bowl, whisk together the fresh orange juice, coconut aminos, honey, minced ginger, minced garlic, and arrowroot starch until the starch is fully dissolved.
Heat the avocado oil in a large non-stick skillet over medium-high heat.
Add the chicken to the skillet in a single layer and sear for 5-6 minutes, turning occasionally, until golden brown and cooked through.
While the chicken cooks, steam the broccoli florets in a steamer basket for 3-4 minutes until they are bright green and tender-crisp.
Reduce the skillet heat to medium and pour the orange sauce mixture over the chicken.
Stir constantly for 1-2 minutes as the sauce bubbles and thickens into a glossy glaze that coats the chicken.
Remove from heat and drizzle with toasted sesame oil for an aromatic finish.
Serve the sticky orange chicken bites over the warm jasmine rice with the steamed broccoli on the side.
